TEHRAN, Iran (AP) _ Landslides triggered by heavy rains killed at least 32 people and injured 45 others in two Iranian provinces, the official Islamic Republic News Agency reported Saturday.

The Natural Disaster Headquarters said it expected the casualties to rise. Some 500 people were involved in the rescue operation.

The news agency said 30 people were killed in the town of Masouleh in the northern Gilan province and two people were killed in the northeastern province of Ardebil. There were fears that more than 100 people may be buried in Masouleh.

The mud slides swept away cars and trucks and damaged a number of homes along the Masouleh River. In Ardebil, flash floods killed livestock and damaged orchards and farms in 20 villages, the news agency said.

Relief workers have rescued 700 stranded villagers. Electricity has been restored to Masouleh, and some 50 cars have been retrieved from the river.

In April, a landslide killed 55 people in a remote village in central Iran.
