One member of Iraninfo-icon's Revolutionary Guards has been killed and five wounded in an attack on a base in southeastern Iran, local mediainfo-icon reported. 

The attack on Saturday came as the country held official celebrations to the mark the 40th anniversary of its Islamic Revolutioninfo-icon.

Mohammad Hadi Marashi, provincial deputy governor for security affairs, told the IRNA state news agency that the attack targeted a base of the Basij, a paramilitary force affiliated with the powerful Revolutionary Guards, in the city of Nik Shahr in Sistan-Baluchestan province.

"A [paramilitary] Basij base in Nik Shahr came under ... fire this morning and several from the Revolutionary Guards communications personnel who were wiring the base were hit," Hadi said. 

"Five of the Guards personnel were wounded and one was martyred," Marashi said, adding that anniversary events were proceeding peacefully.

The semi-official news agency Tasnim said Jaish al-Adl, a Sunni armed group, has claimed responsibility for the attack.

Mohsen Golmohammadi, Nik Shahr's prosecutor, identified the victim as Morteza Aliahmadi in an interviewinfo-icon with the semi-official Mehr news agency. 

The prosecutor said the two attackers scaled the wall of the military base before opening fire. Both assailants escaped, he said. 

Last week, a double-bombing attack injured three policemen in Zahedan, the provincial capital. Jaish al-Adl (Armyinfo-icon of Justice) claimed responsibility for the attack. 

Meanwhile, Iran unveiled a new cruise missileinfo-icon with a range of 1,300 km during celebrations to mark the Islamic revolution. 

"With a range of more than 1,300 km ... this cruise missile needs a very short time for its preparedness and can fly at a low altitude," Amir Hatami, Iran's defence minister, said in remarks carried by state television during the unveiling ceremony.

Hatami said the new surface-to-surface missile, named Hoveizeh, was from the Soumar family of cruise missiles, which were unveiled in 2015.

Western experts say Iran often exaggerates its weaponsinfo-icon capabilities, although there are concerns about its long-range ballistic missiles.

Iran said in January its bid to launch a satellite failed after Tehraninfo-icon ignored USinfo-icon warnings to avoid such activity.

Washington warned Tehran this month against undertaking three planned rocket launches that it said would violate a UN Security Council resolution because they use ballistic missile technologyinfo-icon.

The United Statesinfo-icon is concerned that the long-range ballistic technology used to put satellites into orbit could also be used to launch warheads.
