Plus, Olmert's "deep regret" over crime.
The pattern of the fire made it clear that it came from the Israelis, he said, and only Israel possesses weapons heavy enough to penetrate the fortified bunker protecting the four observers.
The only thing in doubt was how or why an Israeli aircraft came to bomb a clearly marked UN position that should have been exempt from attack.
"This position has been there for twenty years. Israel knows these positions and they have had two weeks to zero in on this area and register targets and where you don't want to hit. That's standard behaviour," the UN source said.
"They (the bunkers) are big white things — you can see them for miles and they are lit up at night. Even if the Israelis just arrived cold from the moon two weeks ago, they have been firing there in that area regularly for two weeks. If you keep firing all afternoon into a position like that, then ultimately something will go wrong."
The UN secretary general Kofi Annan says an Israeli attack on a UN observation post was "apparently deliberate". Four unarmed military observers were killed in the air strike in southern Lebanon. [The Independent]UPDATE 2:
