World leaders have condemned a series of blasts in Sri Lanka that killed more than 207 people and left 450 wounded on Sunday, including dozens of foreigners - with British, Dutch and American citizens believed to be among them. Hospital sources also said Japanese citizens were among those injured by the bombs which ripped through three five-star hotels and churches holding Easter services.

The Netherlands: ‘Terrible reports’ “Terrible reports from Sri Lanka about bloody attacks on hotels and churches on this Easter Sunday,” Dutch Prime Minister Mark Rutte tweeted after the attacks first emerged. “Thoughts are with the victims and their relatives,” said Rutte. Australia: ‘Terrorist attack’ Prime Minister Scott Morrison said Australia was thinking of those killed in a “horrific terrorist attack”. “To the beautiful people of Sri Lanka, Australia sends its heartfelt sympathies and our prayers and our support - and our offer to do whatever we can to support you in this terrible time of need,” he said in a statement. “At this time as Easter Sunday draws to a conclusion here in Australia, our heart goes out to those Christians and all of those other innocents who have been slaughtered today in this horrific terrorist attack.”
