Officials say Pakistan has shut the offices of the international aid group Save the Children in the capital, Islamabad, without giving any reason.

Pakistani officials late Thursday placed a lock on the gate of the group's offices and asked employees to leave.

On Friday, two government officials said the action was taken on orders from the Ministry of Interior

The officials spoke on condition of anonymity because they were not authorized to speak to the media.

Save the Children has previously been accused by Pakistani intelligence agencies of facilitating a Pakistani doctor's vaccinations program in the city of Abbottabad as cover for the CIA to obtain DNA samples at a compound where al-Qaida leader Osama bin Laden was later killed by U.S. commandos.
