US Secretary of State Antony Blinken is set to arrive in Israel on Sunday as part of Washington’s intensifying diplomatic push to achieve a ceasefire in Gaza that will end the 10-month-old onslaught between Israel and Hamas, Reuters reports.

The top US diplomat’s tenth trip to the region since the offensive began in October last year comes days after the United States put forward bridging proposals that it and mediators Qatar and Egypt believe would close gaps between the warring parties.

US officials cite fresh optimism to bring the deal over the finish line but also caution that there is still work to be done.

“What we’ve done is taken the gaps that remain and have bridged those in a way that we think basically is a deal that is now ready to close and implement and move forward,” a senior Biden administration official told reporters on Friday.

In Israel, Blinken is expected to meet with Israeli Prime Minister and other senior officials.
