Deadly blast rocks Lebanese city

At least five people have been killed in a suspected car bomb attack on a military bus carrying soldiers in the northern Lebanese city of Tripoli.

Witnesses said the blast happened on the outskirts of the city during morning rush hour. Some 30 people are believed to be wounded.

Several soldiers as well as civilians were killed in a similar blast on a bus in the city last month.

Lebanon's leaders said the attacks were an attempt to destabilise the country.

Efforts have been under way recently to try and reconcile Lebanon's rival factions after a wave of violence in May pushed the country close to civil war.

Pro-government Sunni fighters and pro-Syrian gunmen, whose fighting has centred on Tripoli, agreed to a peace deal earlier this month.

Threatened deal

Lebanese officials said the blast came after a car parked by a busy roadside near the southern entrance to the city was detonated by remote control.

The explosives were believed to have been mixed with nuts and bolts, and shattered nearby windows and damaged other cars.

The blast appeared to target a military bus that was passing through morning traffic in the Bahsas neighborhood at the time.

Security sources said four of the dead and at least 21 of the wounded were soldiers, the rest were civilians.

TV pictures showed soldiers sealing off the area and preventing people from approaching the scene of the blast.

Government officials said an investigation into the attack was under way, but no one had yet claimed responsibility.

At least 14 people were killed in a similar attack on a bus in the city in August. Several of the victims were off-duty soldiers.

'Terrorist act'

"Once again the hand of treachery has reached the military institution in a clear targeting of security and stability," the Lebanese military said in a statement after Monday's attack.

Parliament Speaker Nabih Berri said the bombing was aimed at undermining efforts to reconcile Lebanon's various rival factions.

Syria too denounced the bombing, calling it a "terrorist and criminal act".

A similar bombing in the Syrian capital Damascus killed at least 17 people just two days ago.

The Syrian authorities have blamed the attack on Islamist extremists, and say the car came from a "neighbouring Arab country".

The BBC's Natalia Antelava says some analysts believe this new trend for car bombings in the region is directly linked to the changing situation in Iraq.

As the security situation improves there, analysts say, so insurgents are driving their members across the border into neighbouring countries.
