Security has been beefed up for Indian diplomats in Pakistan after authorities received intelligence warning that suicide bombers have entered Islamabad to target Indian High Commissioner Satyabrata Pal.

Pakistan's Interior Ministry has directed the Islamabad chief commissioner, acting police inspector general and the Islamabad Diplomatic Enclave Security police superintendent to make foolproof security arrangements for the Indian High Commission in Islamabad after intelligence agencies reported threats of suicide attacks on Indian diplomats, sources said on Friday.

The sources said that according to a letter written by National Crisis Management Cell Director (Operations) Lieutenant Colonel Muhammad Imran Yaqoob to the Islamabad administration, the government had received intelligence reports warning that one out of three women suicide bombers, who have entered Islamabad, would target the Indian High Commissioner Satyabrata Pal.

The Interior Ministry's Foreigners Security Cell officials directed security agencies to send a report after tightening Indian diplomats security, the Daily Times newspaper said Saturday's quoting sources.

An additional force of the Diplomatic Security Police has been deployed outside the Indian High Commission.

The Indian diplomats have limited their movement after they were informed about the threat, the report said.
