T he United States believes the remaining differences between Israel and Hamas can be bridged in negotiations over the Palestinian militant group’s latest ceasefire proposal, as talks resume in Cairo on Wednesday, Reuters reports.

Israeli forces on Tuesday seized the main border crossing between Gaza and Egypt in Rafah, the southern Gaza city where more than one million displaced Palestinians have sought shelter during Israel’s seven-month-old offensive. This cut off a vital route for aid into the tiny enclave, where hundreds of thousands of people are homeless and hungry.

In Cairo, all five delegations participating in ceasefire talks on Tuesday — Hamas, Israel, the US, Egypt and Qatar — reacted positively to the resumption of negotiations, and meetings were expected to continue on Wednesday morning, two Egyptian sources said.

CIA Director Bill Burns was to travel from Cairo to Israel later on Wednesday to meet Israeli Prime Minister Benjamin Netanyahu and Israeli officials, a source familiar with his travel said.
