Now they're at it again, this time pissing on the UK and other Western backers of Israel. Their response says it all:
...the Israeli foreign minister, Avigdor Lieberman, broke his government's
silence saying there was no proof that the Mossad was behind the killing.
In other words: "You got no proof it was me, assholes!"
The Brits are co-operating with the Dubai authorities to try and uncover that proof. Here's hoping they find it.
