A Jordanian national has been arrested for attacking his two Israeli coworkers at the Eilat port in southern Israel on Friday morning, November 30, The Times of Israel reported.

The man used a hammer to attack his colleagues, whom police said were badly wounded in the incident.

Another Jordanian worker was lightly hurt as he struggled to restrain the suspect.

The motivation behind the attack was not immediately clear.

“All possibilities are being investigated at this stage,” police said.

The MDA emergency first responder organization said in a statement:

“At 8:31 p.m., a report was received at MDA’s 101 call center for the Negev region regarding two people who were injured in what appears to have been a brawl between workers on a ship in Eilat.

“MDA paramedics provided medical treatment and evacuated a 24-year-old man in moderate condition with contusions to his upper torso to Yoseftal Medical Center in Eilat, along with a second victim in light condition.”

The suspect started his job at the port on Thursday, November 29, after receiving a daily work permit from the Population and Immigration Authority, according to the Haaretz daily.

In 2014, Israel granted 1,500 Jordanians permission to work in the Red Sea resort town of Eilat.
