The roads to Gulf state's key industrial area Sohar, home to a refinery port and aluminium factory, are blocked by protesters and the city's Lulu supermarket has been set on flames, witnesses said on Monday.

Sultan Qaboos bin Said, trying to ease tensions in the normally sleepy Gulf state as Arab unrest spread in the region, reshuffled his cabinet on Saturday, a week after an earlier protest in the capital Muscat.
Protests were also taking place in the southern town of Salalah where demonstrators have been camped out since Friday near the office of a provincial governor.
After the clashes in Sohar, police pulled back from the protest and the crowd, some of whom were carrying petrol and matches, was making its way to a police station, said one witness, who gave his name only as Mohammed. Helicopters circled overhead.
Witnesses said at least eight people had been hurt in the melee in addition to the two fatalities. Roadblocks had been set up on a main road between Sohar and Muscat, they said.
