Israel's military says it has carried out five airstrikes in Gaza after militants exchanged fire with soldiers.
Brig. Gen. Ronen Manelis said the military struck training camps of the militant Islamic group Hamas that rules Gaza and has been leading protests along the border with Israel.
He said troops exchanged fire with militants on 3 separate occasions.
Manelis said turn out by Monday afternoon was about 40,000. He said the army views that number as a "failure for Hamas."
He said the army noticed there were more women at the front of the protest than in past rallies and accused Hamas of paying people to protest.
