Heavy rain and snow after months of drought have led to floods across Iran in the past week, causing deaths and damage to thousands of properties and roads.

According to reports, the southern regions of the country -- in Sistan-Baluchistan, Kerman, Fars and Hormozgan provinces -- are the worst hit by heavy rains, with higher number of casualties and villages that are left without power and surrounded with water.

Heavy snow, unprecedented in recent years, have chocked off mountain passes. Some areas are blanketed with six feet of snow.

Local authorities said on Wednesday that four people, including three children, were killed in floods in Kerman and Hormozgan provinces, dozens of villages were evacuated and access to more than 300 other villages was cut off.

There is no exact number for the casualties as many people are still missing and communication systems are lost in many of the flood-stricken areas, while relief operations are slow and insufficient. ()

Kerman Governor Ali Zeinivand said at a meeting of the province's crisis management taskforce on Wednesday that the situation in many towns and villages was critical as they are besieged by water, and unless precipitation decreases, flooding cannot be controlled.

Officials from different ministries and organizations, including President Ebrahim Raisi and several military commanders, have been paying visits to the people who are living in temporary housings.
