Iran president dismisses talks with US as 'useless'

Iran's president struck a muscular tone on dealings with the US, saying on Thursday that "talks are useless" as Tehran's nuclear deal with world powers crumbles further.

President Hassan Rouhani made the comment in a speech in Tehran during the unveiling of the Bavar-373, a long-range surface-to-air missile system that he described as an improvement to the Russian S-300.

"Now that our enemies do not accept logic, we cannot respond with logic," Rouhani said in the televised speech.

He added: "When the enemy launches a missile against us, we cannot give a speech and say: 'Mr. Rocket, please do not hit our country and our innocent people. Rocket-launching sir, if you can please hit a button and self-destroy the missile in the air.'"

On Wednesday, Iran's state TV reported that the Bavar-373 is able to recognise up to 100 targets at a same time and confront them with six different weapons.

Since 1992, Iran has developed a homegrown defence industry that has produced light and heavy weapons ranging from mortars and torpedoes to tanks and submarines.

The US re-imposed sanctions on Iran after the Trump administration pulled out of the nuclear deal over concerns about Iran's missile program and regional influence.

President Donald Trump argued that the accord did not limit Iran's ballistic missile program.
