• That figure is the highest Iran has announced for a single day since April 2.
• So far the government has reimposed a lockdown on just one province, Khuzestan on the border with Iraq in the southwest.

The government has largely lifted the closures it imposed after Iran's first cases were confirmed in February but has been watching out for any resurgence in the number of infections.

Health ministry spokesman Kianoush Jahanpour said 2,819 new cases were confirmed across the country in the past 24 hours, bringing the overall total to 146,668.

That figure is the highest Iran has announced for a single day since April 2.

New infections have been on a rising trajectory ever since hitting a near two-month low on May 2.

Jahanpour said that the virus had claimed another 50 lives over the same period, raising the overall toll to 7,677.

So far the government has reimposed a lockdown on just one province, Khuzestan on the border with Iraq in the southwest.

The province remains "red" -- the highest level on Iran's colour-coded risk scale.

"The provinces of Khorasan Razavi, east and west Azerbaijan, Lorestan, Kurdistan, Kermanshah, Hormozgan and Mazandaran are also in a critical situation," Jahanpour said.
