Taliban admits UN suicide bombing
The Pakistani Taliban have claimed responsibility for the suicide bombing at the UN food agency's headquarters in Islamabad.
Taliban spokesman Azam Tariq said that his group was behind the blast and planned more such attacks.
The blast at the World Food Programme offices on Monday killed five people.
The attack pushed the UN to temporarily close its offices in Pakistan and exposed the vulnerability of many international relief agencies working to provide aid to millions of civilians affected by the fight between the government and Islamic militant groups.
Interior Minister Rehman Malik accused the Taliban of carrying out the attack to avenge the killing on August 5 of their leader Baitullah Mehsud in a US drone attack.
Taliban spokesman Azam Tariq confirmed his group was behind the strike in a phone call.
"We proudly claim the responsibility for the suicide attack at the UN office in Islamabad. We will send more bombers for such attacks," he said.
Tariq did not say why the group attacked a UN relief agency. He said its future targets would include Pakistani security officials, government offices and American installations.
Tariq added: "The UN and other foreign (aid groups) are not working for the interest of Muslims. We are watching their activities. They are infidels."
He added that the Taliban would not target Muslim relief groups.
