Annan: Israel deliberately bombed UN observers
Too soon to know if Anan's accusation hold any water, but certainly, this seems to play directly into Hezbollah's hands.
However, it's interesting to note how the Times played the story. The death of the UN observers is not today's main headline, and all it says in the sub-head is "4 From UN Die in Strike" You need to read the article itself to find out what happened.
The conservative Washington Times, however, pulled no punches (and got the facts wrong). Their headline reads: Israeli strike kills 2 U.N. peacekeepers
