The father of a U.S.-Israeli hostage held in Gaza remains hopeful his son is alive after Hamas claimed uncertainty over his fate. The father is urging the U.S. to engage in direct talks to free the remaining hostages abducted by Hamas two years ago. Hamas previously agreed to release the hostage and the bodies of four other Americans, but now says it does not know the fate of the hostage. Fifty-nine hostages remain in Gaza, with fewer than half believed to still be alive.
