Many newspapers around the world have hailed the killing of al-Qaeda's chief in Iraq, Abu Musab al-Zarqawi, as a great victory over a brutal figure.
But many also carry warnings that the al-Qaeda network will continue to flourish despite Zarqawi's death, and that celebrations in Iraq and Washington may be short-lived.
COMMENTARY IN IRAQ'S SOTALIRAQ
The death of this rotten murderer is the first serious step towards imposing security and stability, but it is only the first step on a long road that may be fraught with greater hardships and more sacrifices, particularly as Zarqawi-minded Ba'thists are still on the rampage and terror champions who provided safe havens for Zarqawi are still providing support for his alien affiliates.
COMMENTARY IN IRAQ'S AL-SHARQ AL-AWSAT
Zarqawi is gone... Yet, despite all his gruesome atrocities, there has been no shortage of those amongst us who would hail him when he was alive and will weep him now that he is dead.
COMMENTARY IN IRAQ'S AL-ZAMAN
By sheer coincidence, the shock of President Bush's publicity ratings hitting rock bottom was dwarfed by a sudden and spectacular breakthrough in Iraq, namely the nominees for the ministries of Defence, Interior and National Security being endorsed by parliament.
Then... again by pure coincidence, Zarqawi's hiding-place was spotted and blown to smithereens, along with the prize fugitive inside.
Praise be to God, who has blessed our land with so many happy coincidences and has made our people gullible enough to swallow them all without choking.
Abu Musab al-Zarqawi died on 7 June, 2006. His end came in an integrated operation marked by experience, planning and good use of information... The heroes of the General Intelligence Service have played a continuous role since the terrorist bombings of 9 October targeted civilians in Amman's three hotels... Our battle against terrorism, its symbols and rhetoric has not come to an end. But the end of Zarqawi in this way should be a lesson to terrorists.
COMMENTARY IN PAN-ARAB AL-QUDS AL-ARABI
The killing of Zarqawi will not weaken the Al-Qaeda network in Iraq, instead it will give it more impetus because Zarqawi built a firm base for the organisation.
COMMENTARY IN PAN-ARAB AL-SHARQ AL-AWSAT
Zarqawi's death is an important event which proves that the Iraqi people still need security and military co-operation. The voices which have been calling for the immediate withdrawal of foreign troops have disregarded the reality on the ground, seeking instead to turn Iraq into an empire ruled by Zarqawi.
COMMENTARY IN PAN-ARAB AL-HAYAT
No doubt Zarqawi's regime will weaken and come to an end after its leader's death... However, Zarqawi's death and what happens to his organisation will not have a great impact on the operations of Iraq's opposition forces against the US occupation.
COMMENTARY IN PALESTINIAN AL-HAYAT AL-JADIDAH
It is true that al-Qaeda leader in Iraq Zarqawi saw the US army levelling Falluja's buildings while there were people in them; but does this mean that he should have retaliated against the sectarian collaborators and occupiers by killing the great Arab [film] producer Mustafa al-Aqqad and Shia crowds worshipping in Karbala and Najaf, or turn a Palestinian wedding into a funeral? A crime is a crime no matter what the incentives are... We denounce the US occupiers and their crimes against the Iraqi people the way we denounce the reckless reactions of Zarqawi and his followers.
There was no other conceivable end for Zarqawi but his killing. The man murdered hundreds of innocent Iraqis, and his organisation, al-Qaeda, spread horror and blood in Iraq as well as tears everywhere and killed innocent people in cold blood... This man, with both Ayman al-Zawahiri and Osama Bin Laden, is one of the people who have afflicted Islam and Muslims with disaster. Each of them bears full responsibility for the negative picture that afflicted Muslims everywhere worldwide.
SAUDI ARABIA'S ARAB NEWS
The dividends from hunting down and removing terrorist leaders have been seen in Saudi Arabia where the militants have been broken. The difference with Iraq of course is the power vacuum there and while that continues the chances of someone stepping into Zarqawi's boots cannot be ruled out. But Zarqawi was not the only person killed in yesterday's air raid; others close to him were killed as well. His web of death which extended beyond Iraq...has been torn apart. His removal will embolden ordinary Iraqis to provide greater information about the militants.
COMMENTARY IN LEBANON'S AL-NAHAR
Here is a mere supposition: What if killing Abu Musab al-Zarqawi was the beginning of Iranian-US preparations for dialogue; or more accurately, what if it was the down payment of Iranian goodwill as a prelude to the big deal? If this supposition was true, it would mean the region is looking to some dramatic changes... Unless the government builds on this chance and seizes it to launch new dynamics for its action at the political level through taking decisions and at the security level through addressing the militias problem, most likely the situation will remain as it is; that is more retreat.
IRAN'S TEHRAN TIMES
With the death of Zarqawi, it is thought that al-Qaeda leaders will try to broaden the scope of their terrorist activities and will probably organize a few terrorist operations throughout the world. Therefore, the US and European countries should enlist the support of influential countries in the region in order to counter the ever-increasing wave of global terrorism.
COMMENTARY IN ISRAEL'S HA'ARETZ
All the experts say that even though Zarqawi's death was a blow for the morale of global jihad, the struggle in Iraq will continue as long as the coalition forces remain there.
COMMENTARY IN ISRAEL'S JERUSALEM POST
Obviously there were those in Israel who heaved a sigh of relief Thursday when news of Zarqawi's death was reported. But it is doubtful that this sigh could match the feeling of relief that was obviously felt in the corridors of power in Saudi Arabia, Egypt and Jordan.
REST OF THE WORLD
Zarqawi's death comes at the right time for the Americans who are bogged down in Iraq in a war with no end in sight. This was an announcement that at last contained some good news.
Zarqawi is dead, but what now? ... The death of al-Qaeda's regional chief does nothing to solve the chaos that has reigned since the US invasion in 2003.
COMMENTARY IN TURKEY'S MILLIYET
The killing of Zarqawi is a big blow to terrorism, but both Zarqawi's organisation and the poisonous seeds it spreads remain intact.
COMMENTARY IN TURKEY'S RADIKAL
The US occupation drew foreign jihadists to Iraq and made Iraq an al-Qaeda base. Now the Americans are happy just because they killed the biggest mosquito in a swamp they themselves produced!
COMMENTARY IN AUSTRALIA'S SYDNEY MORNING HERALD
[Zarqawi's death] raises more questions than it answers. The first, before anyone sits back on their laurels, is: who might take his place? It is too easy - and too dangerous - to presume at this stage that because Zarqawi might be gone that the fight is finished.
CHINA'S RENMIN RIBAO
The killing of Zarqawi will not have a major influence on resistance against the occupation, and a fundamental change for the better in the security situation in Iraq will be difficult.
COMMENTARY IN CHINA'S XINWEN CHENBAO
This is a major victory against terrorism by the multinational forces led by the US, and it will have a deterrent effect on terrorists... It is a considerable blow to al-Qaeda.
COMMENTARY IN RUSSIA'S KOMMERSANT
Washington has relieved Osama Bin Laden of a prominent competitor. Mind you, this is unlikely to improve the situation in Iraq... To all appearances, the liquidation of Zarqawi will give the US and the new Iraqi authorities nothing except a short-lived moral satisfaction.
COMMENTARY IN RUSSIA'S IZVESTIYA
Nature abhors a vacuum. Zarqawi may very soon be replaced by a new Iraqi "terrorist number one". And everything will begin again - explosions, chases and raids.
COMMENTARY IN IRISH INDEPENDENT
Yesterday, with an inevitability borne of the utterly false promise that the bloodbath in Iraq is yielding dividends, we were supposed to believe that the death of Zarqawi was a famous victory.
EDITORIAL IN THE TIMES OF INDIA
Until the issues that agitate these sections of the Muslim population are addressed, al-Qaeda and its terrorists will continue to flourish... The world is definitely better off without the likes of Zarqawi and Bin Laden. But it is a sobering thought that Zarqawi has been eliminated almost five years after Bush had promised to smoke out those responsible for 9/11.
The martyrdom of Zarqawi is a tragedy for the Muslim world and an eye-opener for the United States. If the United States does not stop atrocities against Muslims, many such Zarqawis will be born. Therefore, the United States should stop its brutality towards Muslims, withdraw its forces from Iraq and Afghanistan, settle the issues of Kashmir and Palestine and stay clear of aggression against Iran.
