A Hamas leader on Tuesday threatened to not move forward into the next phase of the Gaza ceasefire agreement until more pressure is placed on Israel to open up a key border crossing, cease deadly strikes and allow more aid into the Palestinian territory.

On Monday, Israel's military took journalists into Rafah — the city at Gaza's southernmost point that troops seized last year and largely flattened — as the 2-month-old Israel-Hamas ceasefire reaches a critical point.
