Donald Trump’s Middle East envoy has travelled to Qatar and Israel to kickstart the US president-elect’s diplomatic push to help reach a Gaza ceasefire and hostage release deal before he takes office on Jan. 20, a source briefed on the talks told Reuters.

Steve Witkoff, who will officially take up the position under Trump’s administration, met separately in late November with Israeli Prime Minister Benjamin Netanyahu and Qatar’s Prime Minister Sheikh Mohammed bin Abdulrahman Al Thani, the source said.

Witkoff’s conversations appear aimed at building on nearly 14 months of unsuccessful diplomacy by the Biden administration, Qatar and Egypt aimed at a lasting ceasefire between Israel and fighter group Hamas in Gaza and the release of dozens of Israeli hostages held in the enclave.

The meetings also signal that the Gulf state of Qatar has resumed as a key mediator after suspending its role last month, the source said.

The source added that Hamas negotiators would likely return to the Qatari capital Doha for more talks soon.
