The UN Assistance Mission in Afghanistan (UNAMA) said Thursday it received "credible" reports that dozens of civilians, including women and children, were killed in airstrikes by Pakistan’s military forces in eastern Paktika province.

On Wednesday, the Pakistani military said security forces killed 13 insurgents in an overnight operation in an intelligence-based operation in South Waziristan.

Officials say rare Pakistani airstrikes have targeted multiple suspected hideouts of the Pakistani Taliban inside neighboring Afghanistan, dismantling a training facility and killing some insurgents.
