RAWALPINDI, July 5: The federal government has directed the four provinces and Islamabad Capital Territory (ICT) administration to adopt "unprecedented" security measures for the US installations and embassy in the wake of revelation from a captured militant that his group had planned to use women suicide bombers, official source said.

To further strengthen the security, four platoons of the Frontier Constabulary have been deployed for diplomatic missions security duty, while the police guards have been replaced.

A police source said the federal government had offered "Rangers" to the ICT administration for diplomatic mission duty, but the ICT top police officials believe that the FC personnel are well-trained and more suitable for guard duty rather than the Rangers.
