The 90 Palestinian prisoners that were in Israeli custody have been released, an Israeli prison service spokesperson said in a statement early Monday morning local time – about 80 minutes past the conclusion of Day 1 of the Israel-Hamas ceasefire and hostage exchange deal.

The first three Israeli hostages were released after the ceasefire officially began. Hours later, Israel released 90 Palestinian prisoners and detainees.

The start of a truce prompted celebrations in Gaza, where Hamas militants made a show of force on the streets after 15 months of war. Hours after the first three hostages returned to Israel, it freed 90 prisoners.
