TEHRANinfo-icon:- Iraninfo-icon said on Sunday it would continue missileinfo-icon tests to build up its defences and denied this was in breach of UN resolutions following USinfo-icon allegations that Tehran had tested a new missile capable of carrying multiple warheads.

US Secretary of State Mike Pompeo on Saturday condemned what he called Iran's testing of a medium-range ballistic missile in violation of the 2015 international agreement on the Iranian nuclear programme, from which Washington has withdrawn.

"Missile tests ... are carried out for defence and the country's deterrence, and we will continue this," Brigadier-General Abolfazl Shekarchi, spokesman for Iran's armed forces, was quoted as saying by the semi-official Tasnim news agency.

"We will continue to both develop and test missiles. This is outside the framework of [nuclear] negotiations and part of our national security, for which we will not ask any country's permission," Shekarchi said.

He did not confirm or deny Iran had tested a new missile, the Reuters news agency said.

Earlier, US National Security Advisor John Bolton tweeted: "Iran just test-fired an INF-range ballistic missile capable of reaching Israelinfo-icon and Europe. This provocative behaviour cannot be tolerated."

Iranian foreign ministry spokesman Bahram Qasemi also said Iranian missiles were purely defensive.

"There is no Security Council resolution prohibiting missile programme and missile tests by Iran," said Qasemi.

Addressing Pompeo, Qasemi said: "It is ... ironic that you cite a resolution that you have not only breached through your unilateral and unlawful withdrawal from the [nuclear] accord but that you also encourage others to breach or even threaten to punish and sanction them if they carry it out."

'Provocative, threatening and inconsistent'

UN Resolution 2231 enshrined Iran's 2015 nuclear deal with Britaininfo-icon, Chinainfo-icon, Franceinfo-icon, Germanyinfo-icon, Russiainfo-icon and the United Statesinfo-icon in which Tehran curbed its uranium enrichment programme in exchange for an end to international sanctions.

The resolution says Iran is "called upon" to refrain for up to eight years from work on ballistic missiles designed to deliver nuclear weaponsinfo-icon.

Iran has repeatedly said its missile programme is purely defensive and denied its missiles are capable of being tipped with nuclear warheads, or that it has any intention of developing nuclear weapons through uranium enrichment.

President Donald Trumpinfo-icon pulled Washington out of the nuclear deal, approved before he took office, in May and reimposed sanctions on Tehran.

Trump said the deal was flawed as it did not include curbs on Iran's development of ballistic missiles or on its support for armed proxies in Syriainfo-icon, Yemeninfo-icon, Lebanoninfo-icon and Iraqinfo-icon.

British Foreign Secretary Jeremy Hunt said on Twitterinfo-icon that he was deeply concerned by "Iran's test-firing of a medium-range ballistic missile. Provocative, threatening and inconsistent with UNSCR 2231".

"Our support for [the Iran nuclear accord] in no way lessens our concern at Iran's destabilising missile programme and determination that it should cease," Hunt added.
