Wikipedia with sources: Deif said more than 5,000 rockets had been fired from the Gaza Strip into Israel in a span of 20 minutes at the start of the operation. Israeli sources reported the launch of 4,300 projectiles from Gaza,[26][27] killing twelve and injuring dozens, most of them from the Bedouin community.[30][112][42] Explosions were reported in areas surrounding Gaza and in the Sharon Plain, including Gedera, Herzliyya, Beersheba Tel Aviv, and Ashkelon.[6][113] Air raid sirens were activated in Beer Sheva, Jerusalem, Rehovot, Rishon Lezion, and Palmachim Airbase.[114][115] Hamas issued a call to arms, with Deif calling on “Muslims everywhere to launch an attack”.[42] In the evening Hamas launched another barrage of about 150 rockets towards Israel, with explosions reported in Yavne, Givatayim, Bat Yam, Beit Dagan, Tel Aviv, and Rishon Lezion.[112]
Like I said, if you have any contradictory evidence, please post it for the readers.
