Security forces shot dead four people and made arrests across Syria on Sunday, as funerals were held for protesters and mourners killed in a bloody crackdown which activists said cost 120 lives.

Despite a relative lull, the four people were shot dead and several others wounded in the Mediterranean town of Jableh, near the port city of Latakia, a human rights activist said.

He said the latest violence broke out after a visit to the town by a new regional governor who met local dignitaries in a mosque.

Students, meanwhile, called for a strike and two MPs resigned after bloodshed on Saturday when Syrians swarmed the streets to bury scores of demonstrators killed in protests the previous day.

At least 120 people were killed in the two-day crackdown, the Committee of the Martyrs of the 15 March Revolution said.
