OFFICIALS in Iran have revealed the country quadrupled its uranium-enrichment production capacity amid tensions with the US over Tehran’s atomic programme.

The announcement came after US president Donald Trump and Iran’s foreign minister traded threats on Twitter.

Iranian officials stressed that the uranium would be enriched only to the 3.67% limit set under the 2015 nuclear deal with world powers, making it usable for a power plant but below the required amount for an atomic weapon.

However, by increasing production, the country will exceed the stockpile limitations set by the accord.

Tehran has provided a July 7 deadline for Europe to set new terms for the deal, or it will enrich closer to weapons-grade levels.

Tehran has long insisted it does not seek nuclear weapons, though the West fears its programme could allow it to build them.

Before Iran’s announcement, Trump tweeted: “If Iran wants to fight, that will be the official end of Iran. Never threaten the United States again!”

MEANWHILE Yemen’s Houthi rebels have said they launched a bomb-laden drone into Saudi Arabia, targeting an airport with a military base.

The attack on the Saudi city of Najran was acknowledged by the kingdom as tensions in the Middle East between Iran and the US remain high.

It is not clear if there were any injuries or what the extent of the damage was.

Najran lies on the Saudi-Yemen border and has repeatedly been targeted by the Iran-allied Houthis.

A statement earlier on the state-run Saudi Press Agency quoted Saudi-led coalition spokesman Col Turki al-Maliki as saying the Houthis “had tried to target” a civilian site in Najran.

IN China, the founder of Huawei has said US restrictions on sales to the company will have little impact.

Washington believes Huawei poses a security threat and last week imposed restrictions on technology sales to the company.

Ren Zhengfei told reporters the controls “will have no impact within this company”, but conceded some low-end business might be affected.

AND in Austria, Chancellor Sebastian Kurz, pictured, left, faces a no-confidence vote in parliament next week after his governing coalition collapsed over a corruption scandal.

Speaker Wolfgang Sobotka, a member of Kurz’s conservative People’s Party, set a special session of the legislature for Monday.

Opposition parties wanted it held this week, but Sobotka said he wants to “give space to the EU election campaign”.
