A suicide bomber has killed at least 25 people and injured 63 of the 350 congregants after opening fire and then self-detonating at a Greek Orthodox church in Syria on Sunday.

Syrian Interior Ministry has linked the attack to the jihadist group Islamic State as governments around the world have condemned the attack.

State media says a suicide bomber in Syria attacked a church filled with people near Damascus, the capital, killing at least 22 people and wounding 63.
