Israel's defense minister said Wednesday that troops have recovered the bodies of one hostage from Gaza and is verifying another possible body.

The deal would secure release of a third of the approximately 100 hostages who remain in Gaza, including two dual U.S.-Israeli nationals. In return, Israel would release some Palestinian prisoners.

The body of Youssef Ziyadne, and possibly that of his son, was found after a "complex and difficult operation," an official said.
