Israel's military says it's taken control of a strategic corridor along Gaza's border with Egypt

TEL AVIV, Israel — Three Israeli soldiers have been killed in an ambush by an explosive device in Rafah, the military and media reported, as the Israeli national security adviser said that the war against Hamas militants would likely last through the end of the year.

Three other soldiers were wounded in the blast Tuesday, media reported. The military says at least 290 soldiers have been killed since the ground operation in Gaza began in October.

Israel’s military said Wednesday it has seized control of a narrow corridor that runs along the entire length of Gaza’s border with Egypt, without elaborating.

Israel has said it is carrying out limited operations in eastern Rafah along the Gaza-Egypt border. Palestinians in Rafah reported heavy fighting Wednesday. The United States and other allies of Israel have warned against a full-fledged offensive in the city, warning of a humanitarian catastrophe.

Fighting in Rafah has already spurred more than 1 million Palestinians to flee, most of whom had already been displaced in the war between Israel and Hamas. They now seek refuge in makeshift tent camps and other war-ravaged areas, where they lack shelter, food, water and other essentials for survival, the U.N. says.

Israeli bombardments and ground offensives in Gaza have killed more than 36,000 Palestinians, according to the Health Ministry, which doesn’t distinguish between combatants and civilians.

Israel launched its war in Gaza after Hamas’ Oct. 7 attack in which militants stormed into southern Israel, killed some 1,200 people — mostly civilians — and abducted about 250. Israel says around 100 hostages are still captive in Gaza, along with the bodies of around 30 more.
