Sri Lanka's president has vowed to overhaul state security after several bomb blasts on Sunday killed 359 people and wounded about 500.
On Tuesday (Apr 23), Maithripala Sirisena said warnings had not been shared with him and promised "stern action". The country's Prime Minister Ranil Wickremesinghe said the Islamic State (IS) group may be linked to the blasts.
Funerals are continuing across the country as people try to process last Sunday's attacks.
IS has claimed the attack, although it did not provide direct evidence of its involvement. Police say they have identified eight out of nine attackers, with no foreigners among them.
"Most of them are well educated and come from maybe middle or upper middle class," Deputy Defence Minister Ruwan Wijewardene said on Wednesday. "They are financially quite independent and their families are quite stable financially.
In a televised address late on Tuesday, President Sirisena said he would completely restructure the police and security forces in coming weeks.
