An out-of-season sandstorm has struck the Middle East causing thousands to have medical issues and reducing visibility in region.

The Times of Israel called the storm “a brownish-yellow fog throughout the country.”  The storm has been working across Israel and into Lebanon, Iraq and Syria.  Meteorologists say the storm will be followed by an intense heat wave that will last through the weekend.

Health officials through the region are telling residents to stay inside to avoid breathing problems.  Schools were either closed to keep children inside to avoid the fine particulates in the air.

The head of a major hospital in Damascus told reporters that over 1,200 people had been treated for breathing problems.  At least 100 of the victims were children.

“It is unbelievable. This must be some test,” said Mansour, a Damascus resident, who gave only his first name told the Associated Press. “It’s hot. Temperatures are high and above that we have this dusty weather! It is something beyond reasonable. Enough please!”

The Syrian Observatory for Human Rights reported that some villages such as al-Mayadeen were so short of medical supplies that they ran out of oxygen canisters and had to turn away victims of the storm.
