The Israeli army revealed that the device was detonated.
"No other barrier like this exists in the world today", Defense Minister Avigdor Liberman enthused regarding the combination wall being built underwater and above ground at the northern edge of the Gaza Strip.
Israel Defence Minister on Sunday announced that construction had begun on a marine barrier with the Gaza Strip extending into the Mediterranean Sea.
It added that the strike was also in retaliation for repeated Palestinian attempts to damage the border fence and "security infrastructure" during ongoing border protests.
The defense forces tweeted "No injuries to IDF soldiers were reported. Returning to the land of Palestine".
The Israeli military aggression killed almost 2,200 Palestinians and injured over 11,100 others.
Low-level demonstrations along the border have continued since protests peaked on May 14, when at least 61 Palestinians were killed as tens of thousands of Gazans protested the United States transfer of its embassy in Israel from Tel Aviv to Jerusalem.
Israeli tank shelling killed three members of the Palestinian militant group Islamic Jihad in the Gaza Strip on Sunday, medical officials said, after weeks of border protests that have drawn lethal army fire.
The soldiers arrived at the scene moments later and opened fire at the individuals, who in turn fled back to the Palestinian side of the fence, the Times said.
Low-level demonstrations along the border have continued since protests peaked on May 14, when at least 61 Palestinians died as tens of thousands of Gazans protested the U.S. moving its embassy from Tel Aviv to Jerusalem.
Israel says it is defending its border as well as its communities nearby.
According to Israeli media, the defence ministry ordered the construction of the barrier in the aftermath of the 2014 war with Gaza and after discovering that Hamas fighters had successfully entered Israel by sea.
