Israeli tanks and troops appeared to push their way into the southern Gaza city of Rafah early Tuesday after Jerusalem said a truce offer from the Hamas terror group did not meet its demands and announcing that it okayed moving ahead with the long-threatened offensive, Ednews reports citing The Times of Israel.

The Israeli military said it was conducting “targeted strikes” against Hamas in eastern Rafah, thought to be the terror group’s final stronghold.

Soon after, Israeli tanks entered Gaza near Rafah, reaching as close as 200 meters (650 feet) from the Rafah Crossing terminal with neighboring Egypt, a Palestinian security official and an Egyptian official said. Both spoke on condition of anonymity because they were not authorized to talk to the press.

Gunfire and explosions could be heard in footage aired from the crossing by Egypt’s al-Qahera TV, which showed the Egyptian side of the crossing empty of people. the rumble of tanks and drone of helicopters were also audible.

The Egyptian official said the operation appeared to be limited in scope. He and Hamas’ Al-Aqsa TV said Israeli officials informed the Egyptians that the troops would withdraw after completing the operation.

On Sunday, Hamas fighters near the Rafah crossing fired rockets into southern Israel, killing four Israeli soldiers.
