Palestinian militants in the Gaza Strip launched dozens of rockets toward Israel early Saturday, setting off air-raid sirens across the country.
The sound of outgoing rockets whooshing through the air could be heard in Gaza and sirens could be heard as far away as Tel Aviv during the early morning barrage.
The sirens sounded as far away as Tel Aviv, Israel's business and cultural capital, some 80 kilometres to the north.
The alleged attack comes a day after Israeli soldiers killed four Palestinians in the West Bank.
