Fifteen people were wounded early Wednesday after the Air Force struck targets in Beit Hanoun, in the northern Gaza Strip.
The wounded were taken to hospitals in the area for treatment. Meanwhile, no injuries were reported in another aerial strike, this time targeting an airport in the southern Gaza Strip.
The IDF's Spokesman's office confirmed that the Air Force attacked two terror tunnels in the northern and southern Strip.
"The tunnels were dug about a kilometer away from the border fence, and were meant to enable terrorists to infiltrate Israeli territory and carry out terror attacks against Israeli civilians and soldiers," the army said.
IDF officials stressed that the Gaza attacks came in response to fire directed at Israel Tuesday. Four mortar shells were fired from the northern Gaza Strip at Israeli territory, causing no injuries or damage.
"The IDF will not tolerate any attempt to harm Israeli citizens and IDF soldiers, and will continue to operate with determination and force against any element that utilizes terror against the State of Israel," the army said. "The IDF holds the Hamas terror organization solely responsible for what goes on in the Strip and for maintaining the quiet there."
