BEIRUT: A Syrian airstrike on an ISIS training camp in the jihadist-held east killed 17 militants and a child, an activist group said in a new toll Sunday.
The Saturday strike hit dormitories in the camp in the Euphrates valley town of Tibni in Deir al-Zor province, the Syrian Observatory for Human Rights said.
The child who was killed had been visiting his elder brother who was training with ISIS, the Observatory said.
President Bashar Assad's regime has stepped up its air campaign against the jihadists in recent weeks, carrying out near-daily airstrikes against areas under their control.
The air force also hit jihadist targets in neighboring Hassakeh province late Saturday, the Observatory said.
ISIS fighters have been battling both government troops and Kurdish militia in the northeastern province, which has a large Kurdish population.
U.S. President Barack Obama announced Wednesday that he had authorized the expansion to Syria of the U.S. air campaign against ISIS he launched in early August.
There have been no U.S. strikes so far, but Obama's announcement, which was made in defiance of the Syrian government, drew protests from Damascus and its Iranian and Russian allies
