Bulgaria’s emergency siren system will be tested at 1:00 pm on Monday, April 1, in ten Bulgarian cities, the Interior Ministry has announced.

The cities are Sofia, Burgas, Varna, Ruse, Kardzhali, Smolyan, Pleven, Plovidv, Pazardzhik and Montana.

The test is carried out according the Order for Early Warnings and Announcement of Disasters. The goal is to make a check of the technical state of the sirens and for the citizens to be aware and able to recognize their sound.

The sirens will be accompanied by information in Bulgarian. There will be also a signal marking the end of the emergency alert.
