Suicide bombers have used explosives-laden ambulances to kill at least 21 people and wound many others in the Iraqi cities of Tikrit and Samarra.
The so-called Islamic State (IS) group said it had carried out both attacks. The attack in the holy city of Samarra targeted Shia pilgrims, including Iranians. A queue of vehicles waiting to enter Tikrit was also hit.
Further north, government forces continue to battle IS in Mosul, but deadly street fighting has slowed them. They are facing fierce resistance as they push through the city’s eastern and southern suburbs, blocked by concrete barricades and snipers on rooftops.(BBC,2016)
