A third suspect is in French custody Saturday in connection with an Islamic extremist knife attack that killed three people in a Nice church, as the distraught family of the suspected Tunisian assailant asked to see video footage of what happened. Investigators in France, Tunisia and Italy are trying to determine the motive of chief suspect Ibrahim Issaoui, and whether he acted alone and whether he premeditated Thursday’s attack on the Notre Dame Basilica. Authorities have labeled the attack, which took place amid growing tensions around cartoons published by a French newspaper mocking the Prophet Muhammad, an act of Islamist terrorism.
