TOPSHOTS A rebel fighter fires his machine-gun at Syrian government troops at the citadel in the town of Harem, on the Turkish border, on October 31, 2012. Perched on a mountainside only about two kilometres (1.2 miles) from the border with Turkey, Harem has been surrounded by rebels who have converged on the town by sneaking through groves of olive trees and abandoned houses.
