Israel stepped up its air and ground offensive in Gaza with more attacks on Hamas militants and command posts on Monday, the first anniversary of a war that has destroyed much of the territory and shattered the lives of its people.

Israel has bombed nearly 85 percent of Gaza’s schools in the past year, killing hundreds of children and displaced Palestinians.

Hezbollah, which began firing rockets at Israel on Oct. 8 in support if its ally Hamas, vowed to keep up the barrages despite its recent losses.
