JERUSALEM — The war in the Gaza Strip has reached one of its darkest periods. Israel's blockade of all food and supplies enters its 12th week. The military has launched another major offensive against Hamas, including “extensive” ground operations.

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.
