Heavy flooding continued in Iran on Tuesday as many provinces geared up for days of waterlogged misery and authorities warned of possible floods in the capital Tehran as well the oil-rich south.
President Hassan Rouhani promised compensation for all financial losses and called for the armed forces to help in flooded areas. "I ask the army and the Revolutionary Guards to help with removing the water and with engineering work in which they have significant capabilities and tools," Rouhani was quoted as saying on Tuesday at a meeting of a government crisis group.
Rouhani’s hardline rivals have accused the government of doing too little, too late.
In a meeting broadcast on state television, the president said: "When a city goes under water because of a flood and neighbourhoods face this problem, removing the water is a difficult, heavy task."
The head of the judiciary, Ebrahim Raisi, said that officials who mishandled the disaster and caused the death of civilians could face prosecution, Fars news agency reported.
