St. Petersburg's main airport temporarily halted all inbound and outbound flights Sunday morning due to thick fog shrouding its runways.
Pulkovo Airport's press service said in a statement on its website that airport management took the decision to halt all flights from 8:40 a.m., citing adverse weather conditions.
In a separate statement released lunchtime, the airport's press service said the fog had cleared and that a normal service would be resumed as quickly as possible.
As of midday, at least 38 flights had been delayed by the airport's closure, including 24 departures and 14 arrivals, Interfax reported.
All flights heading for Pulkovo Airport on Sunday morning were rerouted via Moscow, Arkhangelsk or Tallinn, the news agency said.
