Pakistani nuclear arsenal in safe hands: Zardari

President Asif Ali Zardari on Monday ruled out the possibility of Pakistan's nuclear weapons falling into the hands of the Taliban or other radical Islamic groups, saying that the arsenal had been put under "extra security".

"Pakistan's nuclear installations are in safe hands and under extra security," Zardari said in an interview to foreign media.

The concerns over the safety of Pakistan's nuclear arsenal came about after Taliban's recent advance towards the federal capital, which sparked off fears in the US and other countries.

"I want to assure the world that the nuclear capability of Pakistan is under safe hands," he said.

Allaying fears about a possible threat to the security of Pakistan's nuclear weapons, Zardari said the country had a strong command and control system for its arsenal that was fully in place.

US secretary state Hillary Clinton has said one of the prime American concerns, which have been raised with Islamabad and Pakistan's military, is the probabilities of Taliban advancing and wresting "keys to the nuclear arsenal of Pakistan".
