Three hostages released from Gaza are now in Israel in the first test of a fragile ceasefire with Hamas.

The three hostages are Romi Gonen, 24, kidnapped from the Nova music festival, and Israeli-British dual citizen Emily Damari, 28, and Doron Steinbrecher, 31, kidnapped from Kibbutz Kfar Aza.

Later on Sunday, Israel is expected to release around 90 Palestinian prisoners.

A gradual release of 33 captives over the next six weeks has been agreed on.

In exchange, Israel will release almost 2,000 Palestinian prisoners and Palestinians from Gaza who have been detained.

Israel’s military said the three released hostages would undergo an initial medical assessment.
