Palestinians said the school was sheltering displaced people but the Israeli army said it was being used as a command center by Hamas.

Palestinian officials say Israel’s strikes early Tuesday killed at least seven people in Gaza’s southern city of Khan Younis.

As the threat of all-out-war between Israel and Hezbollah has risen, Israel has drawn down its troop presence in Gaza to move key units to its northern border with Lebanon. Still, thousands of soldiers remain in Gaza, carrying out sporadic raids and preventing displaced Palestinians from returning home.
