Russia's London embassy has urged tourists not to visit Britain after Monday's terror attack on Manchester.
In a statement released on the embassy's website, Russians were warned not to travel to Britain unless “absolutely necessary.”
"The British security services have brought the country's terror threat level to the highest classification possible, indicating that an attack is imminent," the embassy said. "Until the situation stabilizes and danger decreases, the embassy advises Russian citizens to refrain from traveling to the United Kingdom, and particularly large cities, unless absolutely necessary."
The embassy also advised Russians currently in the United Kingdom to monitor local news reports, to remain vigilant in crowded places or on public transport, and to delay trips to "cultural events."
The British government raised the country's terror threat level from “severe” to “critical" on Wednesday, two days after after 22-year-old Salman Abedi detonated a home-made bomb inside Manchester Arena. Twenty-two people died in the attack, many of whom were children.
“Critical” is Britain's highest-level of terror alert and signals that an attack is “expected imminently.” Officials have already confirmed that Abedi could have been working as part of a wider cell, and several arrests have already been made.
