ANTAKYA, Turkey — Syrian security forces arrested scores of people across the country on Saturday as mourners took part in the funerals of six protesters killed Friday outside of Damascus, continuing a grim pattern of protest, death, mourning and repression that has been repeated week after week as the uprising in Syria enters its fourth month.

The Syrian Observatory for Human Rights said three people were killed in the security sweep on Saturday, according to Reuters, and two protesters were killed during the funerals.

Syria has been gripped since mid-March by an unprecedented popular uprising against the government of President Bashar al-Assad, whose family has ruled with an iron fist for over four decades. The government has cracked down hard on the protests, killing more than 1,400 people and detaining more than 10,000, according to activists, who estimate that 20 were killed on Friday, 5 of them children.

Violence in the rural northwest has driven more than 11,000 refugees into neighboring Turkey, where the Red Crescent, a local version of the Red Cross, said this week that 17,000 more were waiting to cross the rugged border. Hundreds have also crossed into Lebanon, The Associated Press reported Saturday, citing a Lebanese security official.
