AKIPRESS.COM - At least 207 people have been killed and 450 hurt in explosions at churches and hotels in Sri Lanka, BBC reports citing police.

Eight blasts were reported, including at three churches in Negombo, Batticaloa and Colombo's Kochchikade district during Easter services.

The Shangri-La, Kingsbury and Cinnamon Grand luxury hotels, all in the capital, were also targeted.

A curfew has been put in place "until further notice" and social media networks have been temporarily blocked.

It remains unclear who carried out the attacks, but reports say 13 people have so far been arrested.

Late on Sunday, the country's air force said an improvised explosive device had been found, and disposed of, close to Colombo's main airport.

"A PVC pipe which was six feet in length containing explosives in it was discovered," spokesman Gihan Seneviratne told local media.
