Capt. Eliav Haim Tzapalamus, aged 21, from Haifa, died in an operational incident in southern Lebanon, the military announced on Thursday.
He was a combat officer in the Combat Engineering Corps, 603rd Battalion, 7th Brigade.
Tzapalamus was killed when a Humvee flipped during operational activity in the area of the Litani River.
Three other IDF soldiers were lightly injured in the incident. All three were evacuated to the hospital to receive medical treatment, and their families have been notified.
"It is with a broken heart and deep sorrow that I received the devastating news of the death of Captain Eliav Haim Tzaflemos (of blessed memory), a Haifa resident and active-duty IDF combat officer, who fell in battle in southern Lebanon," Haifa Mayor Yona Yahav said in a Thursday evening statement.
"Eliav set out to defend his people and his country, and he will not return. He was part of Israel’s generation of heroes, young people with dreams, aspirations, and a whole future ahead of them, who shoulder an immense responsibility for the nation's security and the safety of its citizens," Yahav said. "A generation that reminds us all of the meaning of mission, dedication, and love for the land.
"Eliav was the son of Hali, a Haifa Municipality employee, and Beni. Dear Hali, all of us, your colleagues at the Haifa Municipality, are stunned and heartbroken."
"There are no words to comfort a family facing such a terrible loss. The Haifa Municipality family and all the city's residents bow their heads today, embrace you, and share in your profound grief. May his memory be a blessing."
