The Army has deployed nearly 10,000 AI-powered drones to the Middle East since the war with Iran started, according to a U.S. official.

The drones, known as Merops, were developed by Perennial Autonomy, a defense venture backed by former Google CEO Eric Schmidt, and are designed to hunt and destroy enemy drones.

The system has already seen extensive use on the Ukrainian front, where Merops have downed more than 1,000 Iranian-made Shahed drones used by Russia, according to the official.

The Shahed is the same drone being used against U.S. troops in the Middle East.

The U.S. government is offering a "reward of up to $10 million for information on the key leaders of Iran’s Islamic Revolutionary Guard Corps (IRGC) and its component branches," according to the Rewards for Justice website.

The U.S. is looking for information on 10 officials, including Supreme Leader Mojtaba Khamenei, Deputy Chief of Staff in the Supreme Leader Office Ali Asghar Hejazi and Director and Minister of Intelligence and Security Esmail Khatib.

It is also seeking information on unnamed individuals holding key positions, including secretary of the Defense Council, the IRGC commander and advisor to the supreme leader.

A Marine expeditionary unit with 2,200 Marines aboard three U.S. Navy amphibious ships is being ordered to the Middle East, according to two U.S. officials.

The 31st MEU is permanently deployed to Japan and operates in the INDO-PACOM region, but it is now being ordered to head to the Middle East.

Its deployment does not mean that the unit is going to be used as a ground force for use in Iran, but it offers land, amphibious and aviation assets that can be available to military commanders if needed.

This particular MEU also includes a squadron of F-35 fighter jets and a squadron of MV-22 tilt rotor Osprey aircraft.

Twelve healthcare workers were killed in an Israeli airstrike in southern Lebanon, the Ministry of Health said in a statement.

"Twelve doctors, paramedics and nurses who were on shift at the center were martyred, in addition to the injury of a health worker," the statement continued.

The ministry condemned the attack in Burj Qalawia on the town's "primary health care center," saying violence against healthcare workers "contradicts all international humanitarian laws."

The Ministry of Health's statement added that paramedics in Al-Sawana were also killed in an Israeli attack hours earlier.

A post from the spokesperson for the Israeli Defense Forces to Arab media on Saturday said, "as part of its terrorist activities, Hezbollah is making extensive military use of ambulances."

"We warn that the military use of medical facilities and ambulances must be stopped immediately, and we emphasize that if this approach is not halted, Israel will act in accordance with international law against any military activity carried out by the terrorist Hezbollah using those facilities and ambulances," the post said.

The health center in Burj Qalawia is reportedly run by the Islamic Health Society and allegedly has ties to Hezbollah.
