One person was killed and eight wounded in an overnight explosion at an Iraqi military base housing a coalition of pro-Iranian armed groups, officials said on April 20. The full details remain unclear hours after the blast hit the Kalsu military base in Babylon Province south of Baghdad, where regular army, police, and members of Iraq's Popular Mobilization Forces, or Hashed al-Shaabi, are stationed. It comes days after Iran launched an unprecedented assault on Israel, which reportedly responded with a drone strike on the Islamic republic on April 19, amid tensions fueled by the Gaza war.
