ASHKELON, Israel - A Kassam rocket fired by Gaza-based Palestinians landed in the southern industrial area of Ashkelon Wednesday.
The Color Red warning siren alerted workers in the industrial zone and on a nearby kibbutz.
Residents of Ashkelon - located about 12 miles up the coast from northern Gaza - heard the explosion. It was the first to reach Ashkelon in the recent past.
Earlier in the day, two mortar shells fired from Gaza landed in open fields in the Eshkol Regional Council.
No injuries or property damage resulted from any of the strikes.
In response to the attacks, the IDF Spokesperson's Office said the air force "struck a terror tunnel in the northern Gaza Strip and a terror tunnel in the southern Gaza Strip overnight."
"The tunnels were dug one kilometer from the security fence and were intended for infiltrating into Israel and executing terror attacks against Israeli civilians and IDF soldiers. Direct hits were identified," IDF officials said.
Earlier this week, Palestinians detonated an explosives-laden donkey cart near the security barrier in northern Gaza, killing the animal but failing to harm any Israelis.
Meanwhile, the Beersheva District Court sentenced Gaza resident Dafa Abu Adra to a 28-year prison term for attempted murder, active involvement in an illegal organization, conspiracy to commit a crime, transporting a weapon, and transporting information to commit a terror attack.
Adra confessed to firing rockets at an IDF base near the border and at the city of Sderot. He also admitted to planting bombs along the security fence.
The judges ruled that firing rockets on civilians called a “harsh response.”
