In what seems to be puzzling, a river carrying hail and sand is flowing through a desert after torrential rains lashed the Middle Eastern countries in the past few days.

However, it is not clear as to which desert it is. While a video claims it to be the "Rub' al Khali" ("Empty River"), which is the largest contiguous sand desert in the world, another footage says that the phenomenon happened in an Iraqi desert. 

The footage of the river, which is now called the "sand river", was uploaded on video sharing website YouTube on 11 November and has gone viral since then, with more than five lakh people viewing it.

The video shows a river flowing through the desert and a man, believed to be an Iraqi, is also seen taking chunks of hail from it.

Even though the mystery behind this "sand river" is not known yet, people believe that the rare phenomenon is a gift from God to withstand the country's hot temperature.

Meanwhile, the incessant rain in Middle East has reportedly killed many people and has caused massive damage to property in Iraq, Egypt, Israel, Jordan and Saudi Arabia. Iraqi Prime Minister Haider al-Abadi has declared an emergency in areas affected by rain.
