The Red Cross buses have left the Israeli Ofer prison just outside Ramallah on Monday morning. The released prisoners were then met with fireworks and jubilation on the occupied West Bank.
According to the Israeli prison authorities, none of the detainees will be released to Gaza or abroad. Information about their gender and age varies in different media, but the majority of them are said to be women or minors.
Three young women who had been held as hostages by Hamas in Gaza were released earlier on Sunday, after the ceasefire agreement came into effect.
According to the agreement, another 30 people being held as hostages will be released during the first phase of the ceasefire, which lasts for six weeks, as well as hundreds of additional Palestinians being held by Israel.
The next release of hostages and imprisoned Palestinians is planned for Saturday.
During the first phase of the ceasefire, further negotiations will take place on two subsequent phases. The goal is to reach a permanent end to the war.
