Seven people were arrested and three police officers were killed during a security forces raid on a house in the Sri Lankan capital several hours after the attacks, some of which officials said were suicide bombs.
The government declared a curfew in Colombo and blocked access to social media and messaging sites, including Facebook and WhatsApp. It was unclear when the curfew would be lifted.
There were no immediate claims of responsibility for the attacks.
