New Delhi, Oct. 28 Defence Minister A K Antony said on Wednesday said that the tumultuous situation in Afghanistan and Pakistan poses serious security threat to India everyday.

"Whatever is happening in Afghanistan and Pakistan is causing serious concern to us everyday. So land water security is very important, we will have to protect land water for that, we will have to give all support to army and air force," Antony told reporters during Coast Guard Commander's Conference.

Hundreds of civilians were killed in fresh militant strikes in Kabul and in the Pakistani city of Peshawar on Wednesday.

Taliban militants killed six UN foreign staff in an assault on an international guest-house in Kabul whereas a car bomb killed more than 80 people and wounded about 100 in a crowded market in Peshawar.

On the question of deploying army against Maoists in the wake of Rajdhani express' seizure by Naxals in Midnapore, Antony ruled out that option.

"Deployment of the armed forces for internal security is the last resort. When we are convinced that all other agencies are finding difficulties then only as a last resort, we will deploy armed forces not only against Naxalites, but against all other, who poses threat...Army's main role is to protect national interests, security and borders," Antony said.

Hundreds of Maoists stormed a high-speed Rajdhani Express at at Banstala near Jhargram in West Midnapore before security ersonnel took control of it on Tuesday. (ANI)
