CAIRO, Oct 12 (Reuters) - Israeli military strikes on Gaza overnight killed at least 19 Palestinians, medics said on Saturday, while forces continued to push deeper into the Jabalia area, where international relief agencies say thousands of people are trapped.

Israel’s military said it was “operating with great force” against Hamas and allied groups and issued new evacuation orders, as it also continued its campaign in Lebanon.

The deadly strike on the school in Deir al-Balah, central Gaza, killed one child and seven women, according to the Al-Aqsa Martyrs Hospital. Witnesses, speaking anonymously, said the strike occurred while school managers were meeting aid group representatives in a room normally used by Hamas-run police. No police were present at the time.
