The International Security Assistance Force (ISAF) in Afghanistan on Friday fired 'four artillery rounds' inside Pakistan to target Taliban who attacked its bases, an ISAF statement said. "ISAF countered three attempts by insurgent to attack ISAF bases in Bermel district in Paktika (Afghanistan)," an emailed ISAF statement from its Kabul headquarters said. The statement did not say where the Taliban were attacked. It said ISAF soldiers first saw "two insurgents positioning rockets in preparation for an attack. The ISAF troops fired six artillery rounds at the location". "Within an hour, eight rockets were fired at the ISAF base. In response, ISAF fired four artillery rounds at the insurgents inside Pakistan," the statement said.
