Ban Ki Moon wants to appeal directly to Assad to stop.
A ground offensive has begun.
From The Independent,
The battle, news of which is impossible to verify since the electricity supply to the city has largely been cut, came after a Syrian government official said that district of Baba Amr, a rebel stronghold, would be "cleansed".

The fighting would pitch the largely under-armed opposition against Bashar al-Assad's brother, Maher, and his feared 4th Armoured Division, which is understood to have been sent to Homs. "We have nothing to do but pray for them." Abu Yaser, a Homs-based activist, said.

Some activists said they feared an assault on a comparable scale to the 1982 attack on the neighbouring city of Hama in which at least 10,000 people were killed. "The only aim is to repeat the massacre of Hama," a Homs-based activist styling himself Abu Bakr told AFP.
