Major floods across much of Iran have left 19 people dead and more than 90 injured, blocking roads and triggering landslides with warnings of more heavy rain to come, emergency services said Monday.

Such a widespread flood threat is unprecedented in arid Iran, which until 2018 was dealing with decades of drought, reports gulfnews.com.

Seventeen people were killed and 94 injured in the southern city of Shiraz, one person died in the western province of Kermanshah and another in Lorestan, also in the west, rescue services said.

The national emergency has struck in the middle of Iranian New Year holidays, with many relief workers also on vacation.

Many of those killed in Shiraz were holidaymakers caught in the flood as they entered the city in their cars.

With 25 of Iran’s 31 provinces experiencing floods or facing imminent threat, the country’s National Crisis Management Committee was activated at cabinet level.

‘I have ordered all governor-generals, all provincial managers and officials nationwide to stay at their posts throughout the next 72 hours which is the peak of the flood threat,’ First Vice President Eshagh Jahangiri said on state television after the committee’s first meeting.

President Hassan Rouhani issued a statement expressing condolences to victims’ families and thanking emergency services and the military for their responses to the crisis. Since the flooding, Rouhani had previously been absent from public view, with his deputies and ministers taking his place in visiting disaster-struck areas.

Iran’s meteorological service has warned of more heavy showers until Wednesday, forecasting as much as 15 centimetres (almost six inches) of rainfall in some western provinces in the next 24 hours.

The situation is ‘critical’ in the provinces of Khuzestan, Lorestan and Kohgiluyeh-Va-Boyerahmad, said Deputy Interior Minister Mehdi Jamalinejad, quoted by the ISNA news agency.

The latest floods follow major flooding on March 19 in the northeast’s Golestan and Mazandaran provinces, for which no official casualty toll has been issued.

The police have advised against road trips in the coming days, with many roads blocked by flooding or landslides caused by heavy rains.

Tehran’s Mehrabad Airport announced delays or cancellations of flights to the provinces.

The Crises Management Organisation and the health ministry, in charge of hospitals, have cancelled all leave and been placed on full alert.

Local media reported that hundreds of villages have lost electricity and water, many of them cut off as access roads were washed away.

At least 12 people were killed and 68 injured in floods that have swept across most Iranian provinces, the country’s emergency services said earlier on Monday.

National Emergency Service chief Pirhossein Koolivand told state television the initial casualty toll in the southern city of Shiraz was 11 dead and 68 wounded, while another person was killed in Sarpol-e Zahab in the western province of Kermanshah.

Iran has been facing unprecedented floods in 25 of its 31 provinces, the country’s Crisis Management Organisation said.

The latest floods have struck mostly west and southwest Iran and follow major flooding on March 19 in the northeast’s Golestan and Mazandaran provinces, for which no official casualty toll has been issued.

Emergency services have been hampered by Iranian New Year holidays, with many employees on vacation.

The Crises Management Organisation and the health ministry, in charge of hospitals, have cancelled all leave and been placed on full alert, while provincial chiefs have been ordered to remain at their posts.

Iran’s meteorological service has warned that the rains will carry on into Wednesday.
