Syrian government forces rained barrels bombs on Aleppo Thursday, as they pressed a campaign against rebels in the **rthern city where dozens have been killed this week, a monitor said. The Britain-based Syrian Observatory for Human Rights also said jihadist fighters executed 15 civilians in the **rtheastern province of Hasakeh. At least seven children were among those killed by members of the Islamic State of Iraq and the Levant near the town of Ras al-Ain, it said. The Observatory did **t give any immediate toll for Thursday's raids on Aleppo's rebel-held districts, but said regime helicopters dropped barrel bombs on some of the areas.
