Gaza’s Rafah border crossing with Egypt reopened on Monday for limited traffic, a key step in the Israeli-Hamas ceasefire but a mostly symbolic development on the ground as few people will be allowed to travel in either direction and no goods will be going into the war-torn territory.

Within the first hour of the opening, no one was actually seen crossing in or out of Gaza. An Egyptian official said 50 Palestinians would cross in each direction on the first day of the crossing’s operation.

About 20,000 Palestinian children and adults needing medical care hope to leave devastated Gaza via the crossing, according to Gaza health officials. Thousands of other Palestinians outside the territory hope to enter and return home.

State-run Egyptian media and an Israeli security official also confirmed the reopening. The officials spoke on condition of anonymity to discuss the issue.

Before the war, Rafah was the main crossing for people moving in and out of Gaza. The territory’s handful of other crossings are all shared with Israel. Under the terms of the ceasefire, which went into effect in October, Israel’s military controls the area between the Rafah crossing and the zone where most Palestinians live.

Violence still continued across the coastal territory, and Gaza hospital officials said an Israeli navy ship had fired on a tent camp, killing a 3-year-old Palestinian boy.
