DWEIL’A, Syria — A suicide bomber in Syria opened fire then detonated an explosive vest inside a Greek Orthodox church filled with people praying on Sunday, killing at least 22 and wounding 63 others, state media reported.

The attack took place in Dweil’a on the outskirts of Damascus inside the Mar Elias Church, according to state media SANA, citing the Health Ministry for the toll of dead and wounded. Britain-based war monitor the Syrian Observatory for Human Rights said there were at least 19 peopled killed and dozens wounded, but did not give exact numbers. Some local media reported that children were among the casualties.

The attack on the church was the first of its kind in Syria in years, and comes as Damascus under its de facto Islamist rule is trying to win the support of minorities.

As President Ahmad al-Sharaa struggles to exert authority across the country, there have been concerns about the presence of sleeper cells of extremist groups in the war-torn country.

No group immediately claimed responsibility Sunday.
