Washington, Dec 26 (DPA) US President Barack Obama condemned a suicide bombing in Pakistan that left at least 44 people dead at a UN World Food Programme distribution point Saturday.

"Killing innocent civilians outside a World Food Programme distribution point is an affront to the people of Pakistan, and to all humanity," Obama said in a statement issued from Hawaii, where he is spending Christmas with his family.

"The United States stands with the people of Pakistan in this difficult time, and will strongly support Pakistan's efforts to ensure greater peace, security and justice for its people."

A female suicide bomber targeted the crowd collecting food at the distribution centre in Khar. Seventy others were injured in the attack in the Bajaur tribal district, where government forces are fighting Taliban and Al Qaeda militants.

Saturday's bombing targeted the Salarzai tribe, which has joined forces with the government against the Taliban and raised a tribal militia to drive them out of their area. The Taliban took responsibility for the attack in a message sent to various news organizations.
