A total of 207 people were killed and over 450 others wounded Sunday in eight bomb blasts that targeted mainly churches and hotels in Sri Lanka, media reports quoting police said.
Three churches and three luxury hotels were initially hit nearly simultaneously around 8:45 a.m. local time as Easter Sunday masses were in progress, according to the reports.
In the afternoon a seventh blast reportedly occurred at a hotel opposite the national zoo, in an area outside Colombo, killing two people. An eighth blast in a suburb in the north of Colombo followed shortly after, reportedly killing three police officers.
At least 11 foreigners, including two Chinese, were among the dead, according to Press Trust of India. Dutch Foreign Minister Stef Blok said in a tweet that one Dutch national had died.
