BEIRUT: A suicide bomb claimed 29 lives, most of them rebels, near the Syrian town of Al-Bab, which they had taken from the Islamic State group just hours earlier, a state monitor said on Friday. A bomber blew himself up after crashing a vehicle packed with explosives in the Susian area, northeast of the strategic town which the Turkish-backed rebels overran on Thursday after weeks of deadly fighting, the Syrian Observatory for Human Rights said.
