Israel’s military says it has seized control of the entire length of Gaza’s border with Egypt, without elaborating. Capturing the strategic Philadelphi corridor signals that Israel has deepened its offensive in southern Gaza. Palestinians in the border city of Rafah reported heavy fighting Wednesday. Israel previously said it was carrying out limited operations in eastern Rafah along the Gaza-Egypt border. The United States and other allies of Israel have warned against a full-fledged offensive in the city, saying it would cause a humanitarian catastrophe. Earlier Wednesday, a top Israeli official said that Israel’s war with Hamas is likely to last through the end of the year.
