New Delhi - India is set to undertake a security review of key missions in South Asia, starting with Afghanistan, a news report said Wednesday.

Senior officials of the Indian Home Ministry, the Intelligence Bureau, central paramilitary forces and the National Security Guard (NSG) are to begin the review with a visit to Kabul, the Indian Express newspaper reported, citing official sources.

The Indian embassy in Kabul was the target of a suicide bombing in July, in which more than 40 people, including two Indian diplomatic officials, were killed.

Similar reviews of missions in Bangladesh and Sri Lanka were next on the agenda, the sources said.

The Indian embassy in Kabul has issued four advisories from January 17 to 28 on possible threats to Indian nationals.

Besides the embassy in Kabul, India has four consulates in Afghanistan, located in Herat, Mazar-e Sharif, Jalalabad and Kandahar.

The Indo-Tibetan Border Police, which guards the Indian embassy in Kabul, would also be joining the security review.

The NSG, India's elite commando force, is joining such a review for the first time, the Indian Express reported.

Earlier in the week, India sent a paramilitary unit to Pakistan to protect diplomats at its embassy in Islamabad. (dpa)
