UK: Raids will go on
Explosions light up the Belgrade skyline
Defence Secretary George Robertson has told Yugoslav President Slobodan Milosevic that he can only halt further air strikes by ceasing repression in Kosovo.
Foreign Secretary Robin Cook said that the operation had already done "very substantial damage" to Yugoslavia's military assets.
All allied planes involved in the initial strikes, including six British Harrier jump jets, returned to base safely.
The Yugoslav army reported it had suffered casualties on the ground and said 40 sites were hit by Nato.
"We will have to continue to damage the war machine with which he is repressing violently and savagely the people of Kosovo."
He is expected to outline the extent of the damage caused by the strikes at a Ministry of Defence briefing at 1130 GMT.
He also said he would be talking to the Russian Prime Minister Yevgeny Primakov to try to ease Moscow's strong opposition to the air strikes.
The Russian Government fears the Nato operation could lead to the Kosovo conflict spreading to Maecdonia and other countries in the region.
At Parliament there has been broad cross-party support for the raids.
MP Tam Dalyell said: "We won't be able to bomb the Serbs into submission.
"If you were a Serb serviceman and had lost wife and children as has apparently happened in northern Yugoslavia, how would you react?
Lord Healey said the allied action against could have a "catastrophic" effect on western relations with Russia and China.
The former Cabinet minister condemned Nato for acting too quickly and said that the air strikes could result in "serious consequence for the whole world".
"It is quite clear already that Nato has no long-term plan, doesn't know how or when it will get out, whether it will have to put land troops in as well, so it is absolutely vital we resume negotiations," he added.
Hundreds of protesters voiced their opposition to the strikes outside Downing Street overnight. Protests are expected to continue throughout the day.
