“Authorities said the government had received warnings that an obscure Islamist militant organization known as National Thowheeth Jama’ath could stage attacks, possibly targeting religious sites or political figures.”
COLOMBO, Sri Lanka—Sri Lankan authorities took 24 people into custody in connection with a series of Easter morning suicide bombing attacks on tourist hotels and churches that killed almost 300 people and injured hundreds of others.
Arrests were made in several locations in and near the capital, where the bombings were focused. There were at least eight explosions on Sunday, most blamed on suicide bombers.
No one has claimed responsibility for the bombings.
