Much of the southwestern Iranian city of Ahvaz remains inundated by floodwater after being struck with nearly four hours of heavy downpours earlier this week. The Shahrvand newspaper said rain of up to 80 millimeters (3.1 inches) Dec. 17 thrust the city in a state of lockdown, disrupting nearly all public services and prompting a closure of schools, banks and the city's main airport.

The intense showers also triggered an uncontainable release of massive sewage onto streets and homes in a city where officials say the rusting sanitation network is no longer capable of passing on massive rainwater. The city's mayor declared a state of "crisis" as pictures of chaotic scenes, residents submerged in water and makeshift boats sailing across neighborhoods went viral.

"Inundated by mismanagement" read the title of a stinging editorial on the front page of Reformist daily Ebtekar. Similar headlines covered newsstands and a debate on the Iranian government's perceived inadequate response to natural disasters resurfaced.

Yet beyond the disruption and damage, what fanned the fury was the shocking news coming from the city's Imam Khomeini Hospital. Four elderly women in the intensive care unit died after an electricity outage caused by lightning shut down their ventilators, which were connected to malfunctioning emergency power generators. Hospital authorities have confirmed the deaths and the Iranian Ministry of Health is now investigating the incident. This is "management characterized by imprudence," wrote one user on Twitter after the city mayor sought in vain to placate the public anger, saying those who died were already in "terminal condition."
