Save the Children, a charity group that aids children, has been expelled from Pakistan.

Save the Children spokesperson Ghulam Qadri said Pakistan's Interior Ministry gave the charity's foreign staff a two-week notice to leave the South Asian nation.

He said the ministry of interior gave no reason for the expulsion.

According to media reports, the government suspects the group helped facilitate meetings between the United States and Pakistani doctor Shakil Afridi. The physician allegedly helped hunt down Osama bin Laden last May.

Save the Children denied any involvement.

"The allegations that have appeared in the media that Afridi worked with Save the Children and that Afridi was introduced to CIA by our staff, there is no truth to these allegations and no concrete evidence to support them," Qadri said.

"We never knowingly employ anyone who has worked for the CIA or any other security service," he said.

"It is totally against our impartial humanitarian mandate," Qadri explained. "Save the Children is a global organization and has a zero tolerance policy for people involved in work that is not humanitarian."

Save the Children has worked in Pakistan since 1979.
