* Condemnation pours in from around the world 

More than 200 people were killed and at least 450 injured in bomb blasts that ripped through churches and luxury hotels in Sri Lanka on Easter Sunday, the first major attack on the Indian Ocean island since the end of a civil war 10 years ago.

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, many of which officials said were suicide bomb explosions.
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.
"Altogether, we have information of 207 dead from all hospitals. According to the information as of now we have 450 injured people admitted to hospitals," police spokesman Ruwan Gunasekera told reporters.
Three churches in various parts of the country and four hotels in Colombo were hit. At least 27 of the dead were foreigners, including five British people, two of whom had dual U.S. citizenship, and three Indians, according to officials in those countries.
Also among the fatalities were three people from Denmark, two from Turkey, and one from Portugal, officials said. There were also Chinese and Dutch among the dead, according to media reports.
U.S. Secretary of State Mike Pompeo said U.S. nationals were among those killed, but did not give details.
There are 25 unidentified bodies, believed to be of foreigners, at the Colombo Judicial Medical Officer’s mortuary, Sri Lanka's foreign ministry said.
There were no immediate claims of responsibility for the attacks in a country which was at war for decades with Tamil separatists until 2009, a time when bomb blasts in the capital were common.
Prime Minister Ranil Wickremsinghe acknowledged that the government had some "prior information of the attack", though ministers were not told.
He said there wasn't an adequate response and there needed to be an inquiry into how the information was used.
He also said the government needs to look at the international links of a local militant group.
Agence France Presse reported that it had seen documents showing that Sri Lanka's police chief Pujuth Jayasundara issued an intelligence alert to top officers 10 days ago, warning that suicide bombers planned to hit "prominent churches". He cited a foreign intelligence service as reporting that a little-known Islamist group was planning attacks.
A Sri Lanka police spokesman said he was not aware of the intelligence report.
Local Christian groups have said they faced increasing intimidation from some extremist Buddhist monks in recent years. Last year, there were clashes between the majority Sinhalese Buddhist community and minority Muslims, with some hardline Buddhist groups accusing Muslims of forcing people to convert to Islam.
Dozens were killed in one of the blasts at St. Sebastian's Gothic-style Catholic church in Katuwapitiya, north of Colombo. Gunasekera said the police suspected a suicide attack there. Pictures from the site showed bodies on the ground, blood on the church pews and a destroyed roof.
Local media reported 25 people were also killed in an attack on an evangelical church in Batticaloa in Eastern Province.
The hotels hit in Colombo were the Shangri-La, the Kingsbury, the Cinnamon Grand and the Tropical Inn near the national zoo. There was no word on casualties in the hotels, but a witness told local TV he saw some body parts, including a severed head, lying on the ground beside the Tropical Inn.
The first six explosions were all reported within a short period in the morning just as church services were starting.
One of the explosions was at St. Anthony's Shrine, a Catholic church in Kochcikade, Colombo, a tourist landmark.
The explosion at the Tropical Inn happened later and there was an eighth explosion at a house in Colombo. Police and media said that three officers were killed and seven people detained during a raid on this location.
"I strongly condemn the cowardly attacks on our people today. I call upon all Sri Lankans during this tragic time to remain united and strong," said the prime minister in a Tweet.
"Please avoid propagating unverified reports and speculation. The government is taking immediate steps to contain this situation."
President Maithripala Sirisena said he had ordered the police special task force and military to investigate who was behind the attacks and their agenda.
The military was deployed, a military spokesman said, and security stepped up at Colombo's international airport.
Last year, there were 86 verified incidents of discrimination, threats and violence against Christians, according to the National Christian Evangelical Alliance of Sri Lanka (NCEASL), which represents more than 200 churches and other Christian organisations.
This year, the NCEASL recorded 26 such incidents, including one in which Buddhist monks allegedly attempted to disrupt a Sunday worship service, with the last one reported on March 25.
Out of Sri Lanka's total population of around 22 million, 70 percent are Buddhist, 12.6 percent Hindu, 9.7 percent Muslim and 7.6 percent Christian, according to the country's 2012 census.
The heads of major governments condemned the attacks.
US President Donald Trump said America offered "heartfelt condolences" to the Sri Lankan people and stood ready to help, Indian Prime Minister Narendra Modi said there was "no place for such barbarism in our region", and Turkish President Tayyip Erdogan said the bombings were "an assault on all of humanity".
Modi told voters that they needed to elect him to a second term as only he can beat the "terrorists" threatening India. "Should terrorism be finished or not?," he told an election rally in the western state of Rajasthan. "Who can do this? Can you think of any name aside from Modi? Can anybody else do this?"
Pope Francis, addressing tens of thousands of people in St. Peter's Square to hear his Easter Sunday message: "I wish to express my affectionate closeness to the Christian community, hit while it was gathered in prayer, and to all the victims of such cruel violence."
Christians celebrate the resurrection of Jesus Christ on Easter Day after his death on the cross.
Prime Minister Jacinda Ardern of New Zealand, where a gunman shot 50 people dead in two mosques last month, said in a statement: "Collectively we must find the will and the answers to end such violence."
