Russian prosecutors have launched a probe into how bad weather caused massive disruption at Moscow’s two largest airports as passengers staged protests against the chaos that has left thousands stranded. Moscow transportation prosecutor Yevgeny Pospelov said he has launched a probe into the massive delays aimed to protect the rights of passengers.

Freezing weather and power outages have delayed more than 200 flights at Moscow’s Domodedovo and Sheremetyevo airports, with some passengers staging protests in security check areas.

A passenger told international news agency Interfax that passengers in Domodedovo were suffering from lack of ventilation, irregular water supply in airport bathrooms and power outages.

However, power was restored in Domodedovo today after a complete shutdown over the weekend caused by a break in power lines that were weighed down by ice following the freezing rain.
