"An Israeli air strike targeted a vehicle" on the Damascus-Quneitra road, "killing two people", said the Syrian Observatory for Human Rights, without identifying them.

A local security source told AFP that "two charred bodies were removed" from the vehicle that was hit.

The Israeli army did not immediately comment on the reported strike.

Thursday's strike came days after raids blamed on Israel killed 18 people in the central province of Hama, according to Syrian authorities.

The Observatory said those strikes killed 27 people, including six civilians, and targeted a "scientific research area" and other sites in the province's Masyaf area.

Israel declined to comment on those reported strikes.

Israeli raids on Syria surged after the war on Gaza began then eased somewhat after an April 1 strike blamed on Israel hit the Iranian consular building in Damascus, prompting Iran's first-ever direct attack against Israel.
