A suicide truck bomb attack on a security checkpoint on Sunday in Iraq's central Babil province killed at least 51 people and injured another 70. The ISIS terror group claimed responsibility for the attack. The massive blast destroyed the checkpoint buildings and left dozens of vehicles badly damaged, while many civilian cars were set ablaze. Most of the victims were civilians who were inside their cars while in a queue at the crowded checkpoint. The present suicide attack is the second deadliest this year after the February 28 attack that killed 78 people in Sadr city.
