Pakistan police and security sources said aerial bombing in a remote border region killed at least 23 civilians on Monday in an area where militancy has been rising. Pakistani Taliban (TTP) militants have in recent months stepped up a campaign of violence against security forces in the mountainous areas of Khyber Pakhtunkwa province that border Afghanistan. "It was the security force's aircraft that carried out the shelling. Speaking in the Khyber Pakhtunkwa assembly on Monday afternoon, provincial MP Sohail Khan Afridi also blamed the military. Both MPs are members of jailed former prime minister Imran Khan's party which controls Khyber Pakhtunkwa province.
