Israel mounts new sortie into Gaza, hints there may be several 'invasions'

Israel has launched a ground offensive into Gaza, targeting Hamas militants. Prime Minister Benjamin Netanyahu said they were "preparing for a ground invasion" but did not provide details. The move comes after weeks of Israeli bombardment in response to a mass killing spree by Hamas militants. Hamas has threatened to kill hostages it brought back to Gaza, which has raised concerns of a wider war. US President Joe Biden discussed efforts to locate and secure the release of Americans believed held hostage in Gaza during a call with Netanyahu.
