Thomson ReutersISTANBUL (Reuters) - Turkey's military killed at least 28 Islamic State fighters in shelling north of the Syrian city of Aleppo on Sunday in retaliation for the latest attacks against a Turkish border town, broadcaster CNN Turk said, citing a military statement. The attack hit 58 Islamic State targets with artillery and rocket launchers, CNN Turk said on Monday. The pro-government Sabah newspaper reported five people were injured on Friday when rockets fired from Islamic State-controlled territory in northern Syria hit the Turkish border province of Kilis, which is about 60 kilometers (37 miles) north of Aleppo. Kilis has been hit by rockets from Islamic State-controlled territory more than 70 times since January, killing 21 people including children, in what security officials say has gone from accidental spillover to deliberate targeting. The Turkish military usually responds with artillery barrages into northern Syria, but officials have said it is difficult to hit mobile Islamic State targets with howitzers.
