As Russia tries to cut off the flow of information in Ukranian by attacking its communications infrastructure, the British news outlet is reviving a broadcasting tactic from World War II: short wave radio.

The World Service news in English will be broadcast for four hours a day in Kyiv, the Ukrainian capital, and in parts of Russia, thanks to the use of radio frequencies that can travel for long distances and be accessible on portable radios.

It is said that truth is the first casualty of war.

Russian projectiles hit the main radio and television tower. The goal of Russia was to break the resistance of the Ukrainian people and army, according to the defense minister of Ukraine.

Shortwave radio has been used to send messages to soldiers in the Persian Gulf war, send codes to spies in North Korea, and pontificate through the Iron Curtain during the Cold War. More modern forms of radio along with the internet eventually pushed shortwave out of favor, as the BBC retired its shortwave transmissions in Europe 14 years ago.

Over the last week of February, the number of visitors to the site more than doubled from a year earlier. The country's news coverage is provided by the British Broadcasting Corporation via its website, YouTube, Facebook, Telegram, Viber and Espreso TV.

Millions of Russians are turning to the BBC. In the past week, the audience for the Russian language news website reached a record of over 10 million, more than tripling its weekly average. The number of visitors from within Russia to the English language website increased by 25%.

Within the country, there are also updates on Telegram. Other Western news outlets have seen an increase in viewers. The Guardian's digital platforms from Russian and Ukrainian audiences were up 180 percent from January.

Russian officials have complained about the coverage of the BBC. Maria Zakharova, the spokeswoman for Russia's Foreign Ministry, said during a broadcast that Russia was the victim of information terrorism.

Ms. Zakharova did not provide evidence that the British Broadcasting Corporation plays a role in the Russian stability and security.
