Aviva Adrienne Siegel, 62, was released after being taken hostage during the October 7 attack by the Palestinian group Hamas.
In the occupied West Bank, buses from the International Committee of the Red Cross took freed prisoners to Ramallah and Beitunia, greeted by flag-waving crowds Palestinians, Hamas and other factions.
I feel both happy and confused because there is the blood of martyrs in general. I am sad for our martyrs and happy for the victory obtained by our resistance, declared in Beitunia, Yazan Sabah, a young prisoner released as part of this truce.
Israel launched its offensive in the Gaza Strip in the wake of the bloody attack carried out by Hamas in Israeli territory on October 7 which left, according to the Israeli authorities, 1,200 dead, the vast majority of them civilians. The Israeli army estimated the total number of hostages taken to Gaza at 240.
In retaliation for this attack, Israel promised to eliminate the Islamist movement which took power in the Gaza Strip in 2007 and was classified as a terrorist organization by the United States, the European Union and Israel.
According to the Hamas government, 14,854 people, including 6,150 under the age of 18, were killed by Israeli strikes. Gaza Civil Defense puts the number of people missing at 7,000.
If the truce offered respite to Gazans, the humanitarian situation there remains dangerous and the needs are unprecedented, estimates the UN agency for Palestinian refugees (UNRWA).
Since Friday, 248 trucks loaded with aid have been able to enter the Gaza Strip, according to the UN.
We should send 200 trucks per day for at least two months to meet the needs, UNRWA spokesperson Adnan Abou Hasna told AFP , specifying that there was neither drinking water nor food in certain areas.
They're talking about bringing help and fuel, but I've been at the gas station for nine hours and it's still closed, a deplored Sunday in Khan Younès (south) Bilal Diab, a Palestinian interviewed by AFP.
The Israeli army, which considers the northern third of the Gaza Strip a war zone, had already ordered the population to leave and barred anyone from returning during the truce.
Despite this warning, thousands of displaced Gaza residents took advantage of the truce to try to return home to the north.
In Gaza City transformed into a field of ruins, residents walked through the dust on Sunday, between piles of rubble, the streets lined with devastated buildings, according to reports images from AFP.
Moreover, more than half of the territory's housing was damaged or destroyed by the war, according to the UN, and 1.7 million people were displaced, out of 2.4 million inhabitants.
Hospitals in the south of the territory continue to receive many injured people evacuated from the north, where almost all health establishments are at a standstill.
