KHOST (Agencies) An Afghan official said Saturday that 80 Taliban insurgents were killed during an attack on a NATO base near the border with Pakistan. Fresh information that we received from intelligence sources shows that 80 Taliban have been killed. The bodies of the militants were left on the battlefield, said Mukhlis Afghan, spokesman for the governor of eastern Paktika province. NATO said earlier that 30 Taliban had been killed as international troops repelled an attack on the outpost in Barmal district, which sits on the border of Pakistans North Waziristan Agency. A statement from NATOs International Security Assistance Force (ISAF) said the insurgents launched the attack at 1.30 am Saturday (2200 GMT Friday) 'from all directions using rocket-propelled grenades, mortars and small arms fire. Five US soldiers were injured, it said, adding that they kept fighting. The coalition forces called for air weapons team and close-air support during the engagement. A coalition aircraft engaged an insurgent firing position with three precision-guided munitions, it said. The air weapons team also engaged a large number of insurgents near the outpost, it said, adding: Initial operational reporting indicates more than 30 insurgents were killed in the failed attack on the outpost. The proximity of the combat post to the border hints at the possibility the insurgents had crossed from Pakistan, where the Talibans leadership council is believed to be based. The insurgency in Afghanistan is now in its 10th year since the Talibans regime was overthrown in the US-led invasion in late 2001. Remote border regions have proved particularly volatile in recent years. Afghan army general Zemarai, who has only one name, earlier said the bodies of at least 15 insurgents were seen lying on the battlefield after the attack. Taliban spokesman Zabihullah Mujahid said the group had attacked the base, claiming that six police outposts had been overrun in the assault. Speaking by telephone from an undisclosed location, Mujahid said Taliban fighters had inflicted 'high casualties on ISAF and Afghan forces but gave no further details. He said eight Taliban fighters had been killed. NATO said Saturday that two of its soldiers died in separate attacks in the volatile south of Afghanistan, where the insurgency is concentrated. One died in an insurgent attack on Friday, the other in a similar incident on Saturday. The nationalities of the soldiers were not revealed, according to policy. An AFP tally based on that kept by icasualties.org puts the total number of foreign soldiers to die in the war this year at 609, compared to 521 for 2009. NATO and the US have more than 150,000 troops in Afghanistan, many of them deployed to the southern provinces of Kandahar and Helmand in a major counter-insurgency push.
