The so-called Islamic State (IS) says it was behind a bomb attack that killed at least 16 people in the government-controlled Syrian city of Homs.
The group said one of its militants set off the car bomb among "rafidis" - a derogatory term for Shia Muslims.
The attack comes just days after rebels began evacuating the area under a ceasefire deal with the government.
IS has been expanding towards Homs in recent months.
