In a rare incident, heavy snow blanketed the Almas Road in the northwestern Iranian town of Khalkhal nearly one month into the spring.

Reports say the snow is 50 centimeters high and local authorities tried to open the routes after the heavy snowfall.

As a result of the snowfall, temperatures fell in northwestern Iran and even in distant areas.

The region is considered one of the agricultural hubs of the country and the sudden cold snap has caused concern among local farmers during the spring season.
