I think the BBC Weather twitter account (@bbcweather) may have been hacked

Usually the @bbcweather twitter account is pretty non-controversial, not so recently. A couple are rather unpleasant about Israel, promising a nuclear attack on Tel Aviv on Saturday and suggesting that residents of Haifa 'return to Poland'.

 

Other targets for the hackers, apparently Syrian, include Saudi Arabia, Qatar and Turkey.
 
I'm sure normal service will be restored soon and we'll be seeing more tweets like this one from earlier today
