Iranian riot police patrolled a dried-out riverbed in the central city of Isfahan in Iran

Drought and water diversions have been blamed for drying up the Zayandeh-Rood waterway that runs from the Zagros mountains and through the city known for its iconic river bridges.
Water protests since Nov. 9 have drawn at times thousands of demonstrators to the city, where a large rally on Friday escalated into clashes in which 67 people were arrested.
Calm has returned and it held on Sunday, a local photographer said by phone from Isfahan, the country’s third-largest city 340 km south of Tehran.
“In the morning, the city was calm and traffic was normal,” the photographer said.
“I saw riot police patrolling the riverbed between the historic bridges, but their numbers were lower than on Saturday.”
The protesters blame the authorities for diverting water to neighboring Yazd province, which is also desperately short of water.
