Tours in Beirut, Moscow and St Petersburg have now resumed. July will see the return of tours in European cities including Dublin, Belfast and on Malta.
City Sightseeing also plans to resume operations in New York next month and will expand to three new undisclosed locations by the end of the year. The brand now boasts more than 100 destinations in 35 countries.
Enrique Ybarra, president and chief executive, said: "Covid-19 stopped the world and we are all very affected by the terrible consequences it is having on people’s health. It is encouraging to see that some countries are managing to reduce infections, allowing them to return to business.
“We are happy to announce the return of a number of operations, to which some more will be added in the coming weeks.”
