Israel's prime minister says his country is ready to go back to war in Gaza if negotiations for a second phase of the ceasefire deal with Hamas collapses.

The agreement is set to halt a 15-month-old war between Israel and Hamas that has decimated the Strip, killed nearly 47,000 Palestinians and 1,200 Israelis, and destabilised the Middle East.

Israel’s government approved a ceasefire and hostage release deal with Hamas, paving the way for the agreement to take effect Sunday and potentially signalling a new chapter in a bloody 15-month conflict that has enflamed the Middle East.
