A coordinated series of suicide bombings struck Sri Lanka on Easter Sunday, April 21, 2019, targeting three churches during services, St. Anthony's Shrine in Colombo, St. Sebastian's Church in Negombo and Zion Church in Batticaloa, and three luxury hotels in Colombo, followed by two further blasts as police closed in on the attackers. Nine suicide bombers belonging to National Thowheeth Jamaath, a local Islamist extremist group that had pledged allegiance to the Islamic State, carried out the attacks, striking three of the six targets during Easter worship itself and acting in the name of the Islamic State's transnational jihadist ideology.
The bombings were Sri Lanka's deadliest violence since the end of its civil war a decade earlier. The government declared a state of emergency, and the following months saw a wave of retaliatory anti-Muslim violence and mob attacks in several towns, a communal backlash against the country's wider Muslim minority, who had no connection to the attack. The Presidential Commission of Inquiry's 2021 final report found that Sri Lankan state intelligence had received specific advance warning of the plot from a foreign partner service and had not acted to prevent it, and recommended criminal proceedings against several senior officials, including former President Maithripala Sirisena, for the failure. Sirisena has publicly denied responsibility for the failure, telling the BBC that accountability belonged to the officials below him who did not pass on the warning and who were already facing their own prosecution, not to the president.
