Israeli war cabinet member Benny Gantz has warned that unless Hamas frees all hostages held in Gaza by 10 March an offensive will be launched in Rafah. It is the first time Israel has said when its troops might enter Gaza's overcrowded southern city. Global opposition is growing to such an attack in Rafah, where some 1.5 million Palestinians are sheltering. The UN public health agency says a key Gaza hospital had ceased to function following an Israeli raid. The World Health Organization says it had not been allowed to enter Nasser Hospital in Khan Yunis, north of Rafah, to assess the situation.
