At least 28 civilians were killed and 49 injured in airstrikes carried out by Pakistan on its border with Afghanistan, the United Nations Assistance Mission in Afghanistan (UNAMA) said on Monday, Reuters reports.
Pakistan's security forces said they had killed at least 29 militants in ground and air operations along the Afghanistan border, while the Afghan Taliban said at least 38 civilians had been killed in airstrikes.
UNAMA said that the number of casualties could rise as hospitals continue to treat the injured.
Sunday's aerial assault was Pakistan's second on targets in Afghanistan that it said belonged to militants, and threatened to exacerbate an intermittent conflict between the former allies, who fought their worst battle in years in February.
