Hamas released 4 Israeli hostages. There are concerns that the truce won't last long

More hostages return to their homes in Israel. This time 4 soldiers kidnapped on October 7, last year during the Hamas terrorist attack. At the same time, the Israelis disagree with the number of hostages released. Does that mean the ceasefire can end quickly? Palestinians besides return to their homes in Gaza, but most of the buildings in their hometowns have been turned into rubble.
