French authorities detained 72-year-old Hicham Harb, a key suspect in the 1982 grenade and gun attack on a Jewish restaurant in Paris that killed six people. Extradited by the Palestinian National Authority, Harb is suspected of directing the attack. French President Emmanuel Macron praised the extradition as a sign of judicial cooperation. The attack, attributed to a Palestinian splinter group, remains unresolved with no convictions to date. The case has faced legal challenges, and the French government is committed to pursuing justice.
