Israel is pressing deeper into the Gaza Strip with tanks and soldiers as its ground offensive expands in the densely populated Palestinian enclave alongside an air campaign. The Israel Defense Forces said Tuesday that it was “striking in all parts of the Gaza Strip,” despite warning residents to move south for shelter. Later Tuesday, the IDF claimed responsibility for an attack on the Jabalya refugee camp in northern Gaza that killed and injured hundreds of people, according to health officials in Gaza. A senior Hamas commander was targeted and killed in the strike, the IDF said. Exact figures for the dead and injured have yet to be determined amid rescue efforts. Footage from the scene streamed by Al Jazeera showed dozens of people digging through rubble to reach trapped people.
