President Donald Trump has ramped up expectations around a possible 60-day ceasefire in the war in Gaza after he said Thursday that a response from Hamas was expected within the next day.

TEL AVIV/CAIRO, July 4 (Reuters) - At least 15 Palestinians were killed overnight in an Israeli airstrike in Gaza, according to local health officials, as U.S. President Donald Trump said he expected Hamas to respond to his "final proposal" for a ceasefire in Gaza in the next 24 hours.

The deal comes more than 20 months into the conflict -- and more than three months after a previous deal ended.
