Iranian Supreme Leader Ayatollah Ali Khamenei said on Sunday that war was unlikely, but called on Iran's armed forces to boost their defense capacities, according to his official website, as the country faces increased tension with the United States.
On Saturday, Iran announced plans to boost its ballistic and cruise missile capacity and acquire modern fighter planes and submarines to boost its defenses following the US pullout from Tehran's nuclear agreement with world powers.
"Ayatollah Khamenei emphasized that based on political calculations, there is no likelihood of a military war, but added that the armed forces must be vigilant … and raise their personnel and equipment capacities," the website quoted Khamenei as telling commanders of Iran's air force.
"The supreme leader said … the air defense units were a very sensitive part of the armed forces and on the front line of confronting the enemy, and emphasized the need to increase their readiness and capabilities," the website said in its report on the gathering, which was held to mark Iran's Air Defense Day.
Saturday's news of the military development plans came a day after Iran dismissed a French call for negotiations on Tehran's future nuclear plans, its ballistic missile arsenal and its role in wars in Syria and Yemen.
Iranian President Hassan Rouhani said last month that the Islamic republic's military prowess was what deterred Washington from attacking it.
Separately, a senior Iranian diplomat met visiting UK Middle East Minister Alistair Burt and urged swift European action on a planned package of economic measures to offset the US pullout from the accord and the reimposition of sanctions by Washington, the state-run Islamic Republic News Agency reported.
"The imposition of [US] sanctions and pressures and the lack of rapid action by Europe to fulfill their commitments will have serious consequences," Kamal Kharrazi, a former foreign minister who heads a top foreign policy council, told Burt.
Iranian officials have said they would decide whether to quit the 2015 nuclear deal with world powers after studying the European package of economic measures that could help offset US sanctions.
According to the IRNA report, Kharrazi said, "European countries have not been able yet to take necessary measures to secure Iran's interests under the nuclear agreement. … [Burt] said Britain's position is different from that of the United States and we are looking for a European mechanism to make the nuclear accord successful."
In a meeting with senior parliamentarian Heshmatollah Falahatpisheh, Burt referred to the case of a British-Iranian dual national detained in Iran.
"I thank Iran for its humanitarian act to grant Nazanin Zaghari furlough and her meeting with her family, and we hope that this approach will continue until the release and the pardon of such people," Burt said.
Britain is seeking the release of Nazanin Zaghari-Ratcliffe, a project manager with the Thomson Reuters Foundation. She was arrested in April 2016 at a Tehran airport as she was heading back to Britain with her daughter, now aged four, following a visit with relatives. Zaghari-Ratcliffe was released for three days last month.
On what was the first visit by a British minister since US President Donald Trump withdrew from the nuclear deal, Burt also met Iranian Deputy Foreign Minister Abbas Araghchi.
Iranian Foreign Minister Mohammad Javad Zarif said on Saturday the talks with Burt had focused on "access to banking resources and the sale of oil."
In a statement before his visit, Burt said that "as long as Iran meets its commitments under the deal, we remain committed to it as we believe it is the best way to ensure a safe, secure future for the region."
