CIA Director Bill Burns is set to travel to Israel today to meet with Israeli Prime Minister Benjamin Netanyahu, an anonymous source has told Reuters, Al Jazeera reports.

Burns’s visit comes as Israel has launched military operations in Rafah, seized the vital Rafah border crossing with Egypt, and instructed the more than 1 million Palestinians sheltering in the city in southern Gaza to evacuate.

Israel’s Rafah assault has also cast doubt over the viability of ongoing ceasefire negotiations, with delegations from Israel, Hamas, the US, Qatar and Egypt set to meet in Cairo today.
