Thousands of people turned out for the mass funeral for those who died in the violent crackdown in Homs on Friday night.
Unverified videos posted on the internet supposedly shows a procession of people following coffins through the city.
At least 21 people were killed outside Homs on Saturday according to the UK-based Syrian Observatory for Human Rights claims.
Opposition activists claim more than 250 people died on Friday in one of the deadliest nights since the uprising began in March. Security forces are said to have used mortars and shells on Syria’s third largest city.
However, the government has denied the assault on Homs, calling news reports about it part of a “hysterical campaign” of incitement by armed groups against Syria.
