Tanks fired on opposition districts in the central Syrian city of Homs on Friday, killing four and wounding scores more, activists said, in a resumption of heavy shelling from Syrian forces after a few days of relative calm, Reuters reported. "Thirty tanks entered my neighbourhood at seven this morning and they are using their cannons to fire on houses," said Karam Abu Rabea, a resident of the Karm al-Zeitoun district in Homs. An activist in Khalidiya, also a centre of opposition to President Bashar al-Assad, said he had heard mortars landing intermittently in his neighbourhood since the early hours of the morning.
