A suicide bomber has killed at least 12 people at the opening of a local police station in a rebel-held town in southern Syria, rebels and residents say.
Those killed on Thursday included a member of the Western-backed opposition interim government, they said.
They said the bomber, a young man, detonated his suicide vest just as local officials were gathering to inaugurate the police station in the town of Inkhil, 40 kms north of the city of Deraa, the provincial capital.
The minister of local administration in the Western-backed interim Syrian government, Yaqoub al Amar, was killed in the explosion along with several local officials, a resident said.
Issam al Rayes, a spokesman of the Western-backed Free Syrian Army, said the signs were that either Islamic State "or agents of the Syrian authorities" were behind the attack.
