Sri Lankan PM Ranil Wickremesinghe discusses the Easter attacks

Sri Lankan Prime Minister Ranil Wickremesinghe said he feared the deadly Easter Sunday attacks could unleash instability and he vowed to "vest all necessary powers with the defense forces" to act against those responsible in a press conference on Tuesday as Sri Lanka marked a day of national mourning for the victims of the attacks. The six near-simultaneous attacks on three churches and three luxury hotels and three related blasts later Sunday was Sri Lanka's deadliest violence in a decade.
