The Iranian navy unveiled Friday its first division of ships and submarines capable of carrying armed UAVs in light of US President Joe Biden's tour throughout West Asia.

The United States and the Israeli occupation have been mounting accusations against Iran as of late, claiming that Tehran has been using drones and missiles to attack US forces and ships with ties to "Tel Aviv" in the Gulf.

"The first drone-carrier division of the Iranian navy consisting of ships and submarine units carrying all types of drone for combat, detection, and destruction has been unveiled," Iranian state television said. 

Iranian media also highlighted that "all types of the latest advanced drones produced by the military and the defense ministry have flown over the Indian Ocean's waters to demonstrate their capabilities."

The Iranian announcement came as Biden embarks on his trip across West Asia, which so far saw him complete his first leg in occupied Palestine where he signed with Israeli occupation caretaker Prime Minister Yair Lapid a security pact reinforcing the US-Israeli front against the Islamic Republic.

Iranian army commander Abdolrahim Mousavi said on television that Tehran was "aware of the aggressive attitude in the (United States') system of domination, it is necessary to increase our defensive capabilities day-by-day."

"If the enemies make a mistake, (these drones) will present them with a regrettable response," he warned as the Islamic Republic unveiled its advanced UAV division.

The United States tried to curtail Iran's UAV program by imposing sanctions on it in October, accusing the state of supplying the technology to its allies in the region, such as Hezbollah in Lebanon, Ansar Allah in Yemen, and Hamas in the Gaza Strip.

The accusations did not only include Iran's allies in West Asia, as they expanded to Europe; White House national security adviser Jake Sullivan said Monday that Iran planned on delivering "hundreds of drones" to Russia in a bid to help it against Ukraine and the western mercenaries amid the country's ongoing war.

The accusations were dismissed days later by Iranian Foreign Minister Hossein Amir-Abdollahian, who said the claims were "baseless" during a telephone conversation with his Ukrainian counterpart, Dmytro Kuleba.

The unveiling comes just one day after Iranian President Ebrahim Raisi warned that Tehran would have a "harsh and regrettable response" to any mistake committed by Washington or its allies.

During a speech in the western province of Kermanshah, Raisi affirmed that "the great nation of Iran will not accept any insecurity or crisis in the region, and Washington and its allies should know that any mistake will be met by a harsh and regrettable response from Iran."

Earlier, US President Joe Biden and Israeli occupation Prime Minister Yair Lapid committed to denying Iran nuclear weapons, demonstrating solidarity among allies long divided over dialogue with Tehran.

US President Joe Biden discussed with caretaker Israeli occupation Prime Minister Yair Lapid means of integrating "Tel Aviv" in the region, according to a statement following a meeting with the premier.

"At the conclusion of his meeting with Lapid, Biden stated that they spoke of ways to integrate the Israeli occupation into the region and his adherence to his security," Israeli KAN broadcaster reported.

The Israeli leader, on the other hand, said he spoke with Biden about "the Iranian threat, and we believe that this matter is not only a matter of concern for Israel, but the world as a whole [...] there will be no nuclear Iran."

"We spoke about Saudi Arabia and the importance of forming a regional coalition to counter Iran," Lapid added.

Biden signed the "Jerusalem Declaration", which capped his first visit to "Israel" as President. The signing came after he told a local TV station that he was open to "last resort" use of force against Iran - an apparent move toward accommodating Israeli calls for world powers to provide a "credible military threat."

The Declaration, issued to the public ahead of a formal signing ceremony on Thursday, emphasized the United States' unwaning support for "Israel's" regional military advantage and ability to "defend itself alone."
