EXPLAINER-What are the details of the Israel-Hamas hostage deal?

(Updates headline)

Nov 22 (Reuters) - Israel and Hamas have agreed to a pause in fighting in Gaza to allow for the release of 50 hostages held by the militant group in exchange for 150 Palestinians held in Israeli prisons and also to allow for more aid to enter the enclave.

WHAT ARE THE DETAILS OF THE DEAL?

Under the deal, the two sides agreed to a four-day truce so that 50 women and children under the age of 19 taken hostage could be freed in return for 150 Palestinian women and teenagers in Israeli detention.

The 50 hostages, among about 240 taken by Hamas in their Oct. 7 raid on Israel, are expected to be released in batches, probably about a dozen a day, during the four-day ceasefire.

Sides to the deal have called the break in hostilities "a humanitarian pause". The pause will be extended by a day for each additional batch of 10 hostages released, Israel said in a statement.

Hamas said Israel had agreed to halt air traffic over the north of Gaza from 10 a.m. (0800 GMT) until 4 p.m. (1400 GMT) each day of the truce and to halt all air traffic over the south for the entire period. The group said Israel agreed not to attack or arrest anyone in Gaza, and people can move freely along Salah al-Din Street, the main road along which many Palestinians have fled northern Gaza where Israel launched its ground invasion.

Qatar's chief negotiator in ceasefire talks, Minister of State at the Foreign Ministry Mohammed Al-Khulaifi, said that under the deal there would be "no attack whatsoever. No military movements, no expansion, nothing." He said Qatar hoped it would "be a seed to a bigger agreement and a permanent cease of fire."

WHEN DOES THE DEAL START?

Speaking early on Wednesday, the Qatari negotiator said the timing for the start of the truce would be announced within 24 hours.

Israel delayed the start to give time for its Supreme Court to hear a challenge to the deal raised by those who say a truce was too much of a concession to Hamas. A court ruling is not expected to derail the deal.

An Egyptian source said the truce could start as early as 10 a.m. (0800 GMT) on Thursday.

HOW WILL IT BE IMPLEMENTED?

The International Committee of the Red Cross will work in Gaza to facilitate the release of the hostages, Qatar said.

The hostages are expected to be transported through Egypt, the only country apart from Israel to share a border with Gaza.

During the truce, trucks loaded with aid and fuel are expected to cross into Gaza, where 2.3 million people have been running out of food and many hospitals have shut down in part because they no longer have fuel for their generators.
