Sri Lanka's prime minister Ranil Wickremesinghe today admitted the government's "failure" to ensure security which could have prevented the Easter Sunday bombings which killed over 250 people across the island, but refused to take personal responsibility. 

Sri Lankan police, including Special Task Force (STF) personnel are registering details about Muslims living and working in areas of the North-East according to local reports.

STF personnel were gathering information about Muslims in Point Pedro from the divisional secretariat as well as the local mosque.

Police were also visiting mosques in Jaffna town, as well as in and around Mullaitivu town, and asking for details on worshippers, mosque administrators said.

Meanwhile a roundup in Kathankudy, Batticaloa and search operations in Akkaraipatru and Ninthavur in Amparai, Kilinochchi and Jaffna had led to several arrests.

Religious leaders and civil society representatives came together for a memorial event in Mannar to pay tribute to the victims of the Easter Sunday attacks.

The memorial was attended by Muslim, Christian and Hindu leaders as well as civil society and local government politicians.

Attendees wore black ribbons in mourning of the victims killed in the Easter Sunday bomb blasts.

Sri Lankan security forces were deployed across Batticaloa in increased numbers following the Easter Sunday bombings. 

The United States warned today that terrorist groups continue to plan possible attacks in Sri Lanka and may strike with little or no warning. 

"Terrorist groups continue plotting possible attacks in Sri Lanka. Terrorists may attack with little or no warning, targeting tourist locations, transportation hubs, markets, shopping malls, government facilities, hotels, clubs, restaurants, places of worship, parks, major sporting and cultural events, educational institutions, airports, hospitals and other public areas," a security alert from the US embassy in Colombo noted. 

A candlelight vigil was held in New York City’s Union Square on Tuesday for the victims of the Easter Sunday attacks.

One vigil attendee shared that “a collective space for our grief and anxiety was a comfort.”

The vigil contained messages of honoring and lifting up the lives lost, sending love, healing and solidarity for those harmed, grieving the loss of loved ones, and mourning the desecration of sacred sites. Calls were also made for the prevention of profiling and extremist and/or nationalist backlashes, and for intercommunity solidarity and pluralism. The organisers emphasized uniting together against fueling existing tensions between communities, and specifically uniting against Islamophobic rhetoric, policies and narratives as a whole.
