Two Pakistani women and one foreign national were killed on Monday in a bomb blast inside a United Nations office in the capital Islamabad, senior police officials said.
"Three people, one of them a foreigner, were killed in the explosion," senior Islamabad police official Tahir Alam told reporters at the scene. He did not reveal the nationality of the dead foreigner.
Bani Amin, deputy inspector general of Islamabad police operations, said earlier on local television that two of the dead were Pakistani.
"It appears that the bomb was planted inside the office. It was a UN WFP (World Food Programme) office, there were 80 people working in the office at the time," he said.
"Six people have been shifted to hospital. Two people are dead -- they are women, both Pakistanis," Amin said.
"We cannot say if it was a suicide attack until we find body parts."
