A Kurdish fighter walks by a wall bearing a drawing of the flag of the Islamic State (IS) group in the northern Iraqi town of Sinjar, in the Nineveh Province, on November 13, 2015. Iraqi Kurdish leader Massud Barzani announced the "liberation" of Sinjar from the Islamic State group in an assault backed by US-led strikes that cut a key jihadist supply line with Syria.
