Gunmen kill 45 Shiite Muslims riding on a bus in Pakistan
Gunmen stormed a bus in southern Pakistan and ordered its Shiite Muslim passengers to bow their heads before shooting them, killing at least 45 people in the latest attack targeting religious minority, officials said.
Who carried out the attack in the port city of Karachi wasn't immediately clear, as a Pakistani Taliban splinter group and an Islamic State affiliate both claimed the attack. However, some Taliban fighters have pledged their allegiance in recent months to the extremist group that now holds a third of Iraq and Syria in its self-declared caliphate.
