"The Arman anti-ballistic missile system and the Azarakhsh low-altitude air defence system, built by the ministry of defence, were unveiled this morning," the official IRNA news agency said.

The unveiling of the new weapons comes at a time of heightened regional tensions with the war between Israel and Tehran-backed Hamas raging into a fifth month.

Even before the war, Israel and Iran were implacable foes, with Israel fiercely opposed to Tehran's nuclear programme.

In 2023, Israeli Prime Minister Benjamin Netanyahu called for Iran to face a "credible military threat" to prevent it attaining nuclear weapons.

Tehran has always insisted its nuclear programme is peaceful and denies seeking a nuclear bomb.

The Arman missile system revealed on Saturday "has a medium range and a high altitude that can identify targets at 180 kilometres and engage and destroy them at 120 kilometres," Defence Minister Mohammad-Reza Ashtiani said during the unveiling ceremony, IRNA reported.

The agency said the system could take on "six targets simultaneously" while the Azarakhsh defence system can be mounted on multiple vehicle types and "uses radar, electro-optical system and thermal seekers to detect and track its target."

Iran hailed Hamas's surprise October 7 attack but denied any involvement while Tehran-backed militant groups in Syria, Lebanon, Iraq, and Yemen have increasingly attacked US and anti-jihadist coalition troops deployed to Iraq and Syria.

One such attack on January 28 on a base in Jordan killed three US military personnel, leading Washington to launch its own strikes against pro-Iran targets in Syria and Iraq.

The United States, alongside Britain, also launched repeated strikes against Yemen's Iran-backed Huthis in response to the group's persistent attacks on commercial shipping.

The Huthis say their attacks in the Red Sea are in solidarity with Palestinians in war-battered Gaza.
