Syria's Interior Ministry says the sleeper cell behind a deadly church explosion near Damascus belonged to the Islamic State group.

DAMASCUS (Reuters) -Syrian Christians were struggling on Monday to understand why their community was targeted in a suicide attack and whether they can rely on the Islamist-led government's assurances of protection.

At least 20 people have been killed and 52 more are injured in a “terrorist attack” on a church in the Syrian capital on Sunday, according to the country’s health ministry.
