Military sources said 55 jihadists were killed in shelling north of the Syrian city of Aleppo. Three rocket installations and three vehicles were also destroyed in the attacks, on the Suran, Tal El Hisn, Baragidah and Kusakcik regions.

The shellings were apparently in response to the prolific rocket attacks on the Turkish border town of Kilis, about 37 miles north of Aleppo. So far 20 people have been killed and 70 injured by the rocket fire, according to Turkey's state-run Anadolu news agency.

The Turkish military usually responds with artillery barrages into northern Syria, but officials have said it is difficult to hit mobile ISIS targets with howitzers. Turkish officials have also asked for more help to defend the border. Yesterday, 48 ISIS fighters were said to have been killed by US-led coalition air strikes in Syria.

F-16 and A-10 warplanes killed 44 members of the militant group and injured others in Harjalah, Delha, Baragitah and Hawar Kilis, Anadolu said. Four more were killed in separate airstrikes in the Karakopru region, along with gun installations and barracks. That too was reportedly in retaliation to ISIS targeting of Kilis.
