Addressing a press conference here on Wednesday General Safdar took strong notice of the irresponsible and baseless statements by certain leaders about infiltration from Pakistan into Afghanistan.
"I am totally sealing the border. We want to make sure that the parliamentary elections in Afghanistan are held in a peaceful manner," he said.
Meanwhile, army troops arrested six suspected al Qaeda militants in a tribal region close to the Afghan border on Wednesday, after a shootout in which one soldier was killed, a senior military official said.
The shootout broke out after the suspected militants opened fire on troops patrolling in the North Waziristan tribal region.
Lieutenant General Safdar Hussain told Reuters the suspects opened fire as troops tried to search their vehicle, wounding some soldiers.
He said the troops started chasing the militants after the shootout and arrested four of them.
Then as the troops were taking the arrested men away "some militants hiding behind a boulder fired on them again, killing one soldier."
Hussain said the troops later arrested two more suspects, including an Uzbek. He said identities of other suspects were being ascertained. Security forces on Wednesday detained 24 suspected militants after a raid on an Afghan refugee camp near the border with Afghanistan, officials said.
Two of the detainees were Pakistani tribesmen and the rest were Afghans, Abdul Qayyum, the administration chief of the Bajaur tribal area, said following the raid on the camp, which houses an estimated 6,000 Afghanis.
"The operation was part of an ongoing counter terrorism campaign," Qayyum said.
Bajaur lies close to Afghanistan's Kunar province where the US forces have launched operations to track down insurgents from the ousted Taleban regime.
Last week Taleban remnants shot down a US helicopter in Kunar killing all 16 US servicemen on board.
"We recovered a satellite phone and a large quantity of explosives from the camp," Qayyum said.
