Sri Lanka attacks: 'International network' linked to bombings

A wave of bombings that killed 290 people in Sri Lanka on Sunday was carried out with the support of an international network, officials said.

The government has blamed a little-known local jihadist group, National Thowheed Jamath, although no-one has yet admitted carrying out the bombings.

Another 500 people were injured in the suicide attacks on churches and hotels.

Police arrested 24 people in a series of raids and the president's office declared a state of national emergency.

The emergency declaration, which comes into effect from midnight (18:30 GMT) on Monday, will give police and military extensive powers to detain and interrogate suspects without court orders.

On Monday, another blast rocked a street near a church in the capital, Colombo. Police were attempting to defuse explosives in a vehicle used by the attackers when it blew up. It is not yet known if anyone was hurt.

Sri Lankan authorities were warned about a bomb threat from National Thowheed Jamath a full two weeks before the attacks, cabinet spokesman Rajitha Senaratne said at a press conference.

He said that the warnings were not passed on to the Prime Minister, Ranil Wickremesinghe, or his cabinet. Mr Wickremesinghe acknowledged that security services had been "aware of information" but had not acted on the information.

Defence Secretary Hemasiri Fernando told the BBC that the intelligence "never indicated it was going to be an attack of this magnitude".

"They were talking about isolated, one or two incidents. Not like this," he said.

He said "all important departments of the police" were informed about the warning, but acknowledged that no action was taken.

Suspicion of international support

Mr Senaratne said that authorities believed the bombers had international support. "We do not believe these attacks were carried out by a group of people who were confined to this country," he said, adding: "There was an international network without which these attacks could not have succeeded."

A later statement said President Maithripala Sirisena would ask for foreign help to track down the international links to the attackers.

"The intelligence reports [indicate] that foreign terrorist organisations are behind the local terrorists. Therefore, the president is to seek the assistance of the foreign countries," his office said.

A curfew is to be imposed from 20:00 (14:30 GMT) until 04:00 on Tuesday, the government said. A national day of mourning has been scheduled for Tuesday.

Sri Lanka's National Security Council said a "conditional state of emergency" from midnight would target "terrorism" and would not limit freedom of expression.

In another development, the US State Department issued revised travel advice urging greater caution, adding, "Terrorist groups continue plotting possible attacks in Sri Lanka."

How did the attacks unfold?

The first reports of explosions came at about 08:45 local time with six blasts reported within a small space of time.

Three churches in Negombo, Batticaloa and Colombo's Kochchikade district were targeted during Easter services. Blasts also rocked the Shangri-La, Kingsbury and Cinnamon Grand hotels in the country's capital.

Police did not release a breakdown of how many people were killed and wounded at each location.

All the attacks were carried out by suicide bombers, officials said.

Police then carried out raids on two addresses and there were explosions at both. One was in Dehiwala, southern Colombo, and the other was near the Colombo district of Dematagoda in which three officers were killed.

An improvised explosive device - a 6ft-long [1.8m] plastic pipe packed with explosives - was also found and defused near the airport in Colombo.

Police also recovered 87 low-explosive detonators from the Bastian Mawatha private bus station in Pettah, our correspondent reports.

What do we know about the attackers?

There was swirling speculation about who could be behind the attacks and the government restricted access to social media in the aftermath of the bombings.

National Thowheed Jamath was later named by a government spokesman as the main suspect.

The group has no history of large-scale attacks but came to prominence last year when it was blamed for damaging Buddhist statues.

Addressing reports that officials had had prior intelligence of forthcoming attacks, Mr Wickremesinghe said: "We must look into why adequate precautions were not taken. Neither I nor the ministers were kept informed."

A deep wound to the nation

Very few here expected these massive attacks. The co-ordination, sophistication and timing may indicate international support, but it is not clear yet if National Thowheed Jamath, if it is indeed responsible, has links with global jihadist groups.

It is thought that some Muslim youths in Sri Lanka were radicalised after clashes last year in Kandy district between the majority Sinhala Buddhists and Muslims. Videos posted on social media showed hardline Islamists and Sinhala hardliners promoting hatred. But why were the Christians targeted? They are also a minority in Sri Lanka. Sri Lankan Muslims are baffled by the attacks, as well as nervous and afraid.

Sri Lanka has experience of such attacks - suicide bombers were used by Tamil Tiger rebels during the civil war. But the ruthlessness of the these new atrocities is a shock, and the number of dead is a deep wound to the nation, a wound that will take much time to heal.

Who are the victims?

The vast majority of those killed are thought to be Sri Lankan nationals, including scores of Christians who died at Easter church services.

The ministry of foreign affairs said it had identified 31 foreign nationals among the dead, with 14 unaccounted for. The death toll included at least eight British citizens and at least eight citizens of India.

They include three of the children of Danish billionaire Anders Holch Povlsen, a family spokesman confirmed to the BBC. Mr Povlsen owns the Bestseller clothing chain and holds a majority stake in clothing giant Asos.

British lawyer Anita Nicholson died alongside her two children, Alex, 14, and Annabel, 11, when a suicide bomber detonated a device in the breakfast queue at the Shangri-La hotel in Colombo.

Her husband Ben Nicholson survived. "I am deeply distressed at the loss of my wife and children," he said in a statement.

"Anita was a wonderful, perfect wife and a brilliant, loving and inspirational mother to our two wonderful children ... Alex and Annabel were the most amazing, intelligent, talented and thoughtful children and Anita and I were immensely proud of them both and looking forward to seeing them develop into adulthood."
