Admitting that some elements in Pakistan's security forces have turned a "blind eye" to Taliban insurgency, President Pervez Musharraf on Friday said the army or the intelligence agency were not sheltering militants.
"To cast aspersions on the army or ISI is absolutely wrong," Musharraf told reporters in a crowded press conference in this garrison town.
"We had some incidents I know of that in some posts, a blind eye was being turned," he said. "So similarly I imagine that others may be doing the same," he said.
Pakistan, a US ally in the war on terror, has been accused by Afghanistan and Washington of not doing enough to stop Taliban militants from using its soil to launch terror attacks.
He said it was up to the NATO-International Security Assistance Force (ISAF) in Afghanistan to do more to curb militancy and "we refuse to take full responsibility for crossing of the border".
"They must increase their (border) posts and hold the border more strongly." he said. Musharraf also said plans to fence 35 kilometres of its northwestern border with Afghanistan to stop infiltration of Taliban militants were going ahead and construction of the boundary would "take a few months to execute."
"We are doing it, we have decided. The movement of logistics has taken place," Musharraf said, adding, "The area we are fencing at the moment is about 35.2 kilometres in all, they are in seven or eight different pieces," he said.
Pakistan had tried and failed three times to capture top Taliban leader Mullah Dadullah after he crossed over from Afghanistan, he said.
"We know that Dadullah came to Pakistan. Thrice we tried to get him and thrice we failed," he said.
