Syria unrest: Tanks 'reach the centre of Hama'

In Syria it appears military tanks have forced their way to the centre of Hama, a centre of opposition protest.

This unverified footage apparently filmed in Hama on Tuesday, shows tanks on the move and people sheltering from gunfire.

Jim Muir, reporting from neighbouring Lebanon, said there had been a virtual blackout on information, saying "even the local co-ordinating committees... admit they don't know what's going on there".

Earlier the UN Security Council condemned the Syrian government for its deadly crackdown on protesters.
