Syrian rebels shelled Aleppo and air strikes resumed around the city on Friday as Syrian President Bashar al-Assad and his allies said the insurgents’ withdrawal from the city could pave the way toward a political solution for the country.

A day after the last rebels left their remaining pocket of territory in the city, the Syrian Observatory for Human Rights – a war monitor based in Britain – said about 10 shells fell in its southwestern al-Hamdaniya district.

The Observatory said six people, including two children, were killed. State television said at least three people died.

Insurgents seeking to oust Assad have shelled government controlled areas of Aleppo throughout the conflict, which began in 2011. The destruction in those parts of the city has been far less than in eastern districts rebels held until this month.
