Taking into account India's concerns over the military aid to Pakistan, the US Congress has cleared a bill that sets tough conditions on military assistance to Pakistan to make sure that these funds are not diverted to affect the "balance of power in the region".

A press statement from the US state department has said: "Our assistance to Pakistan is designed to meet a common threat. This is a threat not only to Pakistan, but also to the US, and we would argue to India as well, and that's the threat of militant religious extremism. It's not designed against any other neighbor in the region."

India had expressed concern about the security of the Pakistan's nuclear arsenal after militants struck near a nuclear facility in Kamra in Punjab province on Friday.

Foreign Secretary Nirupama Rao said on Friday that India hoped Pakistan government would take steps to ensure its nuclear weapons do not fall into the hands of militants.

The statement holds significance in the wake of an attack near a nuclear facility in the Pakistan Aeronautical Complex within the cantonment in Kamra in Punjab on Friday, which killed seven people. The terrorists struck near a nuclear facility in Pakistan for the fourth time since 2007.
