Islamic State (IS) gunmen have cut the supply route of the Syrian government forces in the northern city of Aleppo, a day after their suicide bombers killed 150 people in Homs and Damascus. Xinhua English reports: The terror-designated group captured three points on the road to Aleppo overnight, said the pan-Arab al-Mayadeen TV. It added that the Syrian army is working on reopening the road, the only supply route for the Syrian government to the city. Other reports said a large convoy of reinforcements has been sent from eastern Aleppo to help recapture the road. Meanwhile, the Syrian Observatory for Human Rights said intense battles are taking place around the road on several fronts. The Syrian army has been making strides against the insurgents in the eastern countryside of Aleppo, Syria’s largest city and once an economic hub. The terror groups were routed out of key areas in Aleppo recently by the Syrian army and the Kurdish-backed Syrian Democratic Forces. The IS action followed the deadly bombings a day earlier which killed over 150 Syrians in the central province of Homs and the capital Damascus in southern Syria.
