The leader of the Islamic State group praised the Easter suicide bombings that killed more than 250 people in Sri Lanka in a video released Monday, calling on militants to be a "thorn" against their enemies in his first filmed appearance in nearly five years.
The video of Abu Bakr al-Baghdadi, to whom the suicide bombers in last week's attack apparently pledged their loyalty, came as the top official in the Catholic Church urged Sri Lanka to crack down on Islamic extremists "as if on war footing."
