NATO's campaign:
The latest NATO blunders involve the deaths of civilians on a bridge, residents of an old people's home in Surdulica and the driver and interpreter in a vehicle carrying western journalists inside Kosovo. Spokesman Jamie Shea (right) insists the bridge, and a building in Surdulica which NATO says was an army barracks, were both "legitimate, designated military targets".
Military spokesman Colonel Konrad Freytag says a tunnel near the area where the journalist convoy was bombed was hit by NATO bombs.
US warplanes begin to arrive in Turkey, the state-run Anatolian news agency reports. They include F-15 and F-16 fighter bombers and C-5 and C-17 cargo planes. Turkey has a small stretch of Balkan territory, making it attractive to NATO planners who wish to surround Yugoslavia and diversify their attack options.
NATO's parliament
In Warsaw, NATO's "parliamentary assembly" - comprising nominee delegates from member parliaments in a purely consultative capacity - are virtually unanimous in their support of the air strikes, although certain "discordant" opinions are expressed.
One Italian deputy is against the resolution, while some 200 parliamentarians from the 19 NATO member-states express their "very clear support", the parliamentary head, Javier Ruperez, tells reporters. "A certain number of discordant voices were heard," he concedes. But he is adamant that this was a minority view.
Refugees:
An Albanian border post less than a mile from the main crossing point used by refugees fleeing from Kosovo is hit five times by Serb tank shells, OSCE monitors report. The post at Pogaj - just across a mountain from the Morina crossing through which hundreds of thousands of ethnic Albanians have poured since late March - is almost completely destroyed. Border police at Morina withdrew a few hundred yards, leaving the checkpoint on the Albanian side of the border deserted, the OSCE say. The KLA have been fighting Serb forces across the border in recent days for control of three small villages. Albanian border police and civilians have been killed and wounded in the crossfire.
The area is around 10 miles from Kukes, where the UNHCR is working to evacuate about 33,000 refugees living in vulnerable camps within Serb artillery range.
Sheaspeak:
Never before in human history have so many people made such an enormous effort to minimise the risk of harm to civilians. NATO pilots do take every precaution to avoid inflicting damage on civilians.
We attack tunnels like this because they can be used for the storage of army equipment and to hide people. This was a legitimate military target and the air crews did not see any civilian vehicles in the area.
We admire the courage of western journalists trying to get into Kosovo to report on the horrors that are going on there. That is an extremely important function, and it's not easy.
But we do not know about the transport of journalists inside Kosovo. That information is not passed to us and we cannot guarantee their security.
There is always a cost to defeat an evil. It never comes free, unfortunately. But the cost of failure to defeat a great evil is far higher.
Democracies are always reluctant to use force: that's the way it should be. But when they are given no choice but to use force to uphold their values, they do not back down.
Our position is clear - no NATO, no go. Because it is crystal clear that if there is not an effective security force in Kosovo, nobody is going to trust that force: no Serb, no Kosovar, nobody.
