JERUSALEM (AP) — Mourners in Israel on Friday were burying the remains of one of the final hostages released in the first phase of the ceasefire between Hamas and Israel, as negotiators discussed a second phase that could end the war in Gaza and see the remaining living captives returned home.

New tensions between Israel and Hamas are raising doubts about prospects for second phase of cease-fire and hostage deal in Gaza.

The United States said talks for a second phase of a Gaza ceasefire deal were on track, as Hamas said Israel agreed to release Palestinian prisoners in exchange for the bodies of four Israeli hostages.
