At least 50 people have been killed and 83 injured in a blast in Afghanistan. It is being reported that a suicide bomber targeted an area near a wedding hall in the capital Kabul. The death toll likely to go up as the health condition of 20 injured is critical. No one immediately claimed responsibility for the attack, but the Taliban and Islamic State affiliates have carried out similar attacks before. Mohammed's birthday is celebrated by Muslims around the world, but extremist groups believe marking it is sacrilegious.
