In the wake of the clashes, Israeli Prime Minister Benjamin Netanyahu cut short his visit to Paris for events to mark the 100th anniversary of the end of World War One and returned to Israel, his office said.
A fresh wave of fighting has erupted between Israeli forces and Palestinian militants in the Gaza Strip, leaving at least six militants dead just as Israel and Hamas had appeared to be making progress toward ratcheting down months of border violence.
It is worth noting that Hamas field commander Nobr Baraka embraced martyrdom as a result of the clashes which claimed one of the Israeli officers and injured one another. It was unclear if the other fatalities included gunmen.
Over the next six months, a Qatari plane loaded with cash will regularly land in Israel and the money will be put into suitcases and driven to the Gaza Strip where it will be distributed to Hamas members, including those in the military wing.
Ten launches from Gaza towards Israel were identified and two were intercepted by Israeli missile defences, the army said. The clashes killed an Israeli lieutenant colonel and prompted Israeli airstrikes and a salvo of rocket fire from Gaza toward Israel.
The IDF revealed Monday morning that Lt. Col "M" had been killed and another soldier injured while operating east of Khan Younis in the Gaza Strip in what had been intended as an "intelligence-gathering operation".

"If this is seen within Israel to be have been a fiasco, this will cause the cabinet, and Prime Minister Netanyahu, a real political headache in the run up to Israeli elections, likely in early 2019, and perhaps provoke further Israeli military action", Lovatt said.
Palestinian officials said that in addition to Baraka, five other Hamas men and a member of the Popular Resistance Committees were killed.
The Israeli military chief, Lt. Gen. Gadi Eisenkot, said a "special force" carried out "a very meaningful operation to Israel's security", without elaborating.
Last week, Israel allowed Qatar to deliver $15 million in aid to Gaza's cash-strapped Hamas rulers.
Hamas has led weekly protests since March 30 in an effort to ease an Israeli-Egyptian blockade that was imposed in 2007 in order to weaken the militant group. Hamas responded by lowering the intensity of Friday's border protest.
"We held serious discussions", he said ahead of his flight to Paris, where he will join world leaders marking the centenary of the end of World War I.
Netanyahu had on Saturday evening defended his decision to allow Qatar to transfer the cash to Gaza, despite criticism from within his own government, saying he wanted to avoid a war if it wasn't necessary.
The blockade has led to over 50 per cent unemployment and chronic power outages, and prevents most Gazans from being able to leave the tiny territory.
