NEW DELHI: The Pakistan High Commission in Delhi has asked the Indian government to enhance its security after recent hate-letters threatened to harm its diplomats and their families, diplomatic sources said on Wednesday.

They were confirming a report in the Times of India on Wednesday which said that fearing threats to its establishments and diplomats in India, Pakistan has sought more security from the Indian government.

Official sources confirmed that the Pakistan high commission had received letters in the past few days threatening to harm its officials. High commission officials on Tuesday took up the issue with India’s Ministry of External Affairs.

The Times said Pakistan has demanded that the letters be thoroughly probed and the identity of senders ascertained. It conveyed to India that it is New Delhi’s responsibility to ensure the security of Pakistan high commission and all its diplomats and other staff.

An Indian government source told the Times that security agencies had been sensitised about the threat mails, one of which was forwarded by the Pakistan high commission. “We provide maximum possible security to all missions and same is the case with Pakistan,” he said.

There was no confirmation about who sent the threat mails.
