ISLAMABAD: The United Nations Security Council said on Friday it condemned a suicide bombing at a mosque on the outskirts of Islamabad that killed at least 32 people, calling the attack “heinous and cowardly” and urging accountability for those responsible.

The blast targeted the Qasr-e-Khadijatul Kubra mosque and imambargah in the Tarlai Kallan area during Friday prayers on Feb. 6, when mosques across the country were packed with worshippers. Daesh claimed responsibility, saying one of its militants detonated an explosive vest inside the congregation.

In a press statement issued by Council President James Kariuki of the United Kingdom, members of the 15-nation body expressed “deepest sympathy and condolences” to the families of the victims and to the government and people of Pakistan.

“The members of the Security Council condemned in the strongest terms the heinous and cowardly suicide bombing terrorist attack,” the statement said, reaffirming that “terrorism in all its forms and manifestations constitutes one of the most serious threats to international peace and security.”

The Council underlined the need to hold “perpetrators, organizers, financiers and sponsors” accountable and urged all states to cooperate actively with the Pakistan government in accordance with international law and relevant UN resolutions.
