Islamabad: Resurgence of Taleban and remnants of al-Qaida are probably the "biggest threat" to Afghanistan's security situation, Chairman of the US Joint Chiefs of Staff Gen Richard Myers has said.

"It's a resurgence of the Taleban and remnants of al-Qaida that do not want to see success inside Afghanistan," Myers told private Pakistani Geo TV when asked about Afghanistan's security situation.

"They like to go back to Afghanistan that existed a couple of years where the terrorist organisations like al-Qaida could have training camps, could do the kind of operational planning that led to not only Sept 11 in the US but other terrorist acts in the area. So that's probably the biggest threat," he said.

Myers, who held talks with Pakistani military officials on the situation in the region, said the US will be there for some time to continue to give the Afghani people some hope.

On Afghan accusations that Pakistan is still secretly supporting the Taleban, he said the role Islamabad has played has been very important.

"The number of al-Qaida that have been arrested here in Pakistan either by Pakistani authorities or in conjunction with US and other countries is a very high number; it's by far the majority of leadership of al- Qaida and that's good for everybody," he added.
