More than 1,000 dead after 2 days of clashes and revenge killings in Syria

The death toll from two days of clashes between Syrian security forces and loyalists of ousted President Bashar Assad and revenge killings that followed has risen to more than 1,000, a war monitoring group said Saturday, making it one of the deadliest acts of violence since Syria's conflict began 14 years ago.

The Britain-based Syrian Observatory for Human Rights said in addition to 745 civilians killed, mostly in shootings from close distance, 125 government security force members and 148 militants with armed groups affiliated with Assad were killed. It added that electricity and drinking water were cut off in large areas around the city of Latakia.

U.S. Secretary of State Marco Rubio condemned the killings in a statement Sunday.
