Israel says it has launched 'extensive' new ground operations in Gaza. Meanwhile, airstrikes killed at least 103 Palestinians overnight and forced a hospital to close.

Israel's offensive is the largest since the ceasefire ended in March, the Israeli military said. Dozens of children were killed, hospitals and medics said.
