The Latest | Israel's military seizes the Gaza side of the Rafah border crossing with Egypt

An Israeli tank brigade has seized control of the Gaza Strip side of the Rafah border crossing with Egypt, authorities say, moving forward with an offensive in the southern city even as cease-fire negotiations with Hamas remain on a knife’s edge.

The move comes after hours of whiplash in the Israel-Hamas war, with the militant group on Monday saying it accepted an Egyptian-Qatari mediated cease-fire proposal. Israel, meanwhile, insisted the deal did not meet its core demands. The high-stakes diplomatic moves and military brinkmanship left a glimmer of hope alive — but only barely — for an accord that could bring at least a pause in the 7-month-old war that has devastated the Gaza Strip.

The Israeli 401st Brigade entered the Rafah crossing early Tuesday morning, the Israeli military said, taking “operational control” of the crucial crossing. It’s the main route for aid entering the besieged enclave and exit for those able to flee into Egypt.

More than a million people are huddled in tents and overcrowded apartments in Rafah after fleeing Israel’s military offensive in other parts of the Gaza Strip. Israel says Rafah is Hamas' last stronghold, but the United States opposes a full-scale invasion of the city bordering Egypt unless Israel provides a “credible” plan for protecting civilians there.

The war in Gaza has driven around 80% of the territory's population of 2.3 million from their homes and caused vast destruction to apartments, hospitals, mosques and schools across several cities. The death toll in Gaza has soared to more than 34,500 people, according to local health officials.

The war began Oct. 7 when Hamas attacked southern Israel, killing around 1,200 people, mostly civilians, and abducting about 250 others.
