In Pakistan, at least 42 people were killed and more than a dozen critically injured Thursday when gunmen opened fire on a convoy of 200 vehicles traveling through a remote northwestern region near the Afghan border. Witnesses say about 10 assailants appeared to target Shia Muslims, first attacking a police escort before firing indiscriminately on buses and cars. It’s the latest in a series of deadly sectarian clashes between majority Sunnis and minority Shias in Pakistan’s Khyber Pakhtunkhwa region that have killed dozens of people in recent months.
