CAIRO (AP) — Israeli Prime Minister Benjamin Netanyahu said Friday his government was considering “alternative options” to ceasefire talks with Hamas after Israel and the U.S. recalled their negotiating teams, throwing the future of the negotiations into further uncertainty.

Israel’s military said it fired warning shots to distance a crowd “in response to an immediate threat” and it was not aware of any casualties.

Twenty-one months into Israel’s war in Gaza, the enclave is gripped by escalating scenes of death and hunger, with some killed while trying to reach aid, others dying of starvation and growing condemnation of Israel’s conduct even among many of its closest allies.

Hamas has reportedly taken steps to fend off possible Israeli military plans aimed at rescuing the 50 remaining hostages in Gaza.

Appearing on Sunday Morning with Trevor Phillips, Bob Geldof said this month, a thousand children or people have died of starvation.

For years, Gazans haven’t had free access to this precious natural resource. Israeli limits on fishing activities have fluctuated with tensions with Hamas, with limits of just three nautical miles and even previous total bans on fishing imposed at times.

Those killed in the strikes include four people in an apartment building in Gaza City among others, hospital staff and the ambulance service said.

Six months in an Israeli military prison and branded a traitor by friends – it has been a tough year for Itamar Greenberg. The 19-year-old Israeli Jew made the rare decision to refuse conscription to the IDF last August as it waged its devastating war in Gaza.
