Israel's ambassador to London Zvi Heifetz accused the mayor of expressing sympathy for Palestinian militants.

"It is outrageous that the same mayor who rightfully condemned the suicide bombing in London as perverted faith', defends those who, under the same extremist banner, kill Israelis," he said in a statement.

Actually I don't think that's what he's said at all. Understanding why someone would be angry enough to go to this sort of bombing is not the same as condoning it. In fact, it's probably the most important thing in preventing more people from taking that route.
