BEIRUT: Sporadic clashes hit the southern edges of Aleppo on Sunday morning, a monitoring group said, hours after rebels said they had broken a three-week government siege of the Syrian city. An alliance of rebels, Islamists, and jihadists late on Saturday said they had opened a new route into Aleppo’s eastern neighborhoods, home to some 250,000 people. But the road, which passes through southern edges of the city, remains too dangerous for civilians to use, the Syrian Observatory for Human Rights said on Sunday. “There are intermittent clashes and air strikes, but to a lesser degree,” said Observatory head Rami Abdel Rahman. “Not a single civilian has left the eastern districts because the road is too dangerous and not secured,” he told Agence France-Presse. On Saturday, anti-regime groups overran a series of buildings in a military academy on the southwestern edges of Aleppo.
