На русском языке:
В Минске будут звучать сирены — это проверка системы оповещения
На беларускай мове:
У Мінску будуць гучаць сірэны – гэта праверка сістэмы абвесткі
The Ministry of Emergency reported that a comprehensive test of the warning system will be held in Minsk until December 2, which will involve electrical sirens and public address systems.
In other words, sirens will be heard in Minsk in the next few days. The Ministry of Emergency reported that such inspection is conducted once a year.
We note that the statement of the Ministry of Emergency Situations about «once a year» is false, since the previous test of the warning system was on March 23.
