Dust storm hit the city of Dehloran in southwestern province of Ilam on Tuesday for a third time in few days, IRNA reported. Dense dust has had residents remain at homes to keep safe from the possible damages.
A local health official Abdolsaheb Sharifi told IRNA that those suffering from heart and respiratory problems have to avoid leaving their homes and if they had to, they should wear surgical masks.
When there is choking dust, it's much recommended to drink milk, especially for those suffering from respiratory diseases, Sharifi said.
The main source of dust storms in Iran are deserts in neighboring Arab countries, Iraq in particular. Having 430 kilometers of joint borders with Iraq, Ilam, in recent years, has repeatedly been subject to dust storms, inflicting heavy damages on the less-developed province.
