Toxic Rain Threat Looms Over Tehran After Israeli Strikes on Oil Sites

GUWAHATI: The residents of Tehran faced a polluted sky which stayed dark throughout Sunday because officials issued warnings about potential toxic rain which could occur after Israeli forces attacked vital oil facilities situated close to the Iranian capital.  

The Iranian Red Crescent Society issued a warning that city rainwater could contain dangerous chemical substances that would result in skin burning and breathing difficulties. The warning comes amid widespread reports of a persistent smell of burning fuel lingering across Tehran after the overnight attacks.

Residents described an unusual scene on Sunday morning, saying thick smoke clouds and heavy haze kept the city unusually dark even after sunrise. Some residents reported that they saw blackened clouds overhead of the capital city which produced rain that appeared to have an oily or contaminated quality. 

The public should stay inside their homes. Emergency officials have urged people to remain inside their homes, even after the rainfall ends. The concerned authorities issued a warning that heated surfaces would cause acidic droplets to evaporate which would result in dangerous airborne toxins reaching their highest levels. 

The Red Crescent reported that explosions at oil storage facilities released substantial amounts of hydrocarbon compounds and sulphur gases and nitrogen oxides which can cause severe respiratory health problems when people breathe them in. 

Officials mandated that residents must clean all food packaging materials which they must do before opening sealed containers because tiny acidic particles will not become visible until they touch surfaces. People were further encouraged to replace older water filters as polluted rainwater could jeopardize their filtration equipment. 

Israeli Strikes Hit Oil Infrastructure 

Israeli forces conducted airstrikes to target four oil storage facilities and one oil-transfer station located between Tehran and Alborz Province. Iranian media reported that at least four tanker drivers were killed in the attacks. 

Videos circulating online showed large fireballs rising into the night sky, with flames lighting up the city’s skyline. The analysts determined that this strike represented the inaugural attack which targeted a civilian energy production facility during the armed conflict.

By Sunday morning, the thick haze reportedly reduced visibility across Tehran. Vehicles moving along major roads, including Valiasr Street, were seen driving with headlights on while security personnel directed traffic wearing masks and protective clothing. 

The Israel Defense Forces declared the installations which they bombed were essential for Iran's military operations. The Israeli military states that the facilities function as a fuel distribution network which supplies multiple sectors including defense operations. 

Israel described the attacks as part of a broader effort to degrade Iran’s military capabilities. 

The current situation develops during an intensifying conflict which involves Iran, Israel and the United States. The conflict escalated on 28 February when US and Israeli forces conducted joint strikes which targeted Iranian military and naval facilities and resulted in the deaths of Iranian leadership members. 

Iranian forces launched missile and drone strikes against Israeli and US military bases throughout the Middle East as their conflict with Israel and the US expanded into a regional war. 

Cities such as Dubai, Abu Dhabi, Manama, Doha and Riyadh reported explosions linked to falling debris from intercepted missiles and drones. 

The confrontation has now entered its ninth day, with tensions continuing to rise and no immediate signs of a ceasefire. US President Donald Trump has demanded Iran's "unconditional surrender" which has resulted in increased diplomatic pressure against Tehran.
