(AP) -- The Israeli military says it has resumed airstrikes on Gaza after Hamas militants violated a de-escalation brokered by Egypt.

Military spokesman Lt. Col. Peter Lerner says that after holding its fire for six hours Israel has "resumed operational activities."

The military says that during the six hours Gaza militants fired about 50 rockets all over Israel. No injuries were reported.

The de-escalation period was meant to lead to detailed cease-fire talks between Israel and Hamas and end a week of fighting that has killed more than 190 Palestinians and exposed millions of Israelis to rocket fire from Gaza.

Israel accepted the Egyptian truce plan, but vowed to hit Gaza hard if Hamas rejected the deal.
