A senior security official based in Islamabad told the AFP news agency that the helicopters had been repelled by both army troops and soldiers from the paramilitary Frontier Corps (FC).
"The helicopters were heading towards our border. We were alert and when they were right on the boundary line we started aerial firing. They hovered for a few minutes and went back," the official said.
"About 30 minutes later they made another attempt. We retaliated again, firing in the air and not in their direction, from both the army position and the FC position, and they went back."

'Crisis in relations'
The two countries held talks last week on anti-militant co-ordination.
America's top military officer, Admiral Mike Mullen, flew to Islamabad to try to calm the crisis in relations but tensions remain high, our correspondent says.
The Americans stepped up their strikes after criticism that Pakistani troops were unable or unwilling to eliminate Taleban sanctuaries along the border.
Waziristan is one of the main areas from which Islamist militants launch attacks into Afghanistan.
It emerged earlier this month that US President George W Bush has in recent months authorised military raids against militants inside Pakistan without prior approval from Islamabad.
Pakistan reacted with diplomatic fury when US helicopters landed troops in South Waziristan on 3 September. It was the first ground assault by US troops in Pakistan.
Pakistan's army has warned that the aggressive US policy will widen the insurgency by uniting tribesmen with the Taleban.
