A 12-year-old girl has been reported dead and three other people injured after Cyclone Mekunu struck southern Oman with high winds and rain.

The girl died after wind swept her against a wall, police say.

State TV showed large areas of flooding in Dhofar and al-Wusta provinces, with dozens of vehicles submerged.

The cyclone intensified in strength on Friday but has now been downgraded and officials said it would weaken further into a tropical storm.

Cyclone Mekunu's landfall to the west of Salalah, Oman's second city, came a day after it lashed the Yemeni island of Socotra, where at least seven people were reported to have been killed.

Thousands of residents near coastal areas in Dhofar and al-Wusta had been moved to shelters as 170km/h (105mph) winds and torrential rain hammered the region, officials said.

About 10,000 people had been evacuated from schools and government buildings, mainly in Salalah, civil defence authorities said.

Forecasters warned of flash floods, saying that Salalah could see at least 20cm (7.87in) of rain - twice the average amount for a whole year.

Authorities have told residents to stay inside and Salalah's airport has been closed until midnight on Saturday local time (20:00 GMT).
