A dust storm blanketed Iraq again on Tuesday, sending people to hospital with breathing difficulties and leading airports to suspend flights.

It follows a similar storm that blew over the country late last week and left dozens hospitalized with respiratory problems.

The latest weather event cast an orange hue over the capital Baghdad, where it severely restricted visibility and coated buildings and cars in dust. 

Pedestrians wore disposable masks to avoid inhaling the particles, AFP journalists said. 

"People have been hospitalized with breathing difficulties, but most cases are minor," health ministry spokesperson Saif al-Badr told AFP. 

Dozens of flights were suspended in Baghdad and the Shiite holy city of Najaf during the morning, before flights resumed in the afternoon when conditions improved, airport sources said.

While sand and dust storms are not uncommon during the Iraqi spring, they are expected to become even more frequent "due to drought, desertification and declining rainfall," said the director of Iraq's meteorological office, Amer al-Jabri. 

Iraq is particularly vulnerable to climate change, with record low rainfall and high temperatures in recent years.

Experts have said these factors threaten social and economic disaster in the war-scarred country.

In November 2021, the World Bank warned that Iraq could suffer a 20 percent drop in water resources by 2050 due to climate change.
