US President Donald Trump took to Twitter on Monday to warn Iran that it will never develop a nuclear strike capacity.

His comments follow Iran’s announcement that it would no longer commit to uranium enrichment limits set under the 2015 nuclear deal after the killing of Quds force commander general Qasem Soleimani.

Tehran also said that it would allow inspections by the International Atomic Energy Agency (IAEA), which was another key requirement of the nuclear accord. 

Monday saw US president’s advisor Kellyanne Conway say that Trump was still open to re-negotiating the 2015 nuclear deal with Iran if Tehran wanted that.

“If Iran wants to start behaving like a normal country… sure, absolutely,” she is cited as saying at a press briefing by Reuters.

Previously, the EU, which is also signatory to the 2015 deal, urged Iran to honor the agreement.

Soleimani’s killing in a drone strike in Baghdad that also left his key ally in Iraq dead greatly increased the frictions between Washington and Tehran, with the late general seen as de-facto the second most powerful person in Iran.

On Monday, a massive mourning ceremony was held in Tehran for Soleimani, with millions reportedly chocking the streets to lament his death
