Via a Washington Post blog:

Secretary of State Hillary Clinton has been privately asking foreign leaders to “dial down” criticism of Israel until all the facts of the flotilla attack are known, according to a source who personally discussed the matter with her.
“She says she’s been working the phones for last 24 hours trying to get people to cool off a little bit, to see what the facts are,” the source tells me, adding that she said she was trying to “dial down some of the rhetoric of the inernational community.”
