Iran’s vice-president has been diagnosed with coronavirus, state media have reported, as the country struggles to stop the spread of the disease.

Masoumeh Ebtekar is among 254 people infected with the virus in the Middle Eastern nation, where 26 people have been killed by the outbreak.

She is better known internationally as the English-language spokeswoman for the hostage-takers who seized the US embassy in Tehran in 1979, sparking a 444-day diplomatic crisis.

Coronavirus cases in Iran spiked by 106 over the last 24 hours, the country’s health ministry announced on Thursday. The country’s death toll from the outbreak is higher than any country except China, where the epidemic began.

The outbreak has prompted Iranian authorities to cancel Friday prayers in Tehran. Health ministry spokesman Kianush Jahanpur said there were also plans to impose restrictions at some holy Muslim sites but the plan “needs the approval of the president before being carried out”.

Mr Jahanpur, speaking to state TV, urged Iranians to avoid “unnecessary trips inside the country”.

State news agency IRNA said Chinese citizens have been banned from entering the country. Similar restrictions have been implemented by dozens of other nations including the US, Russia, South Korea and Australia in a bid to stem the spread of coronavirus.
