Israel on Sunday said it had recovered the bodies of six hostages in Gaza, including a young Israeli-American man who became one of the most well-known captives held by Hamas as his parents met with world leaders and pressed for his release.

The military said all six had been killed shortly before the arrival of Israeli forces. Their recovery sparked calls for mass protests against Prime Minister Benjamin Netanyahu, whom many Israelis blame for failing to bring them back alive in a deal with Hamas to end the 10-month-old war. Negotiations over such a deal have dragged on for months.
