The first phase, spanning a 42-day ceasefire, would see the exchange of 33 Israeli hostages in Gaza for Palestinians held in Israeli prisons, U.S. officials said.

Qatar’s prime minister on Wednesday announced a ceasefire agreement between Israel and Hamas, pausing the devastating 15-month war in Gaza and clearing the way for dozens of Israeli hostages to go home.

The deal will take place in three different phases, each of which will last for six weeks, according to U.S. and Qatari officials.
