Aircraft alarms sound throughout Ukraine on Monday and residents are urged to seek shelter.

The governor of the Mykolaiv region, Vitaly Kim, writes on Telegram that 14 Russian bombers of the Tu-95 type should be in the air.

- It is a part of the Russian strategic bombing campaign that they have been doing since Surovikin took command, says Joakim Paasikivi.

Electricity and infrastructure targets

Explosions have been reported from several parts of the country.

Kyiv Independent writes on Twitter that explosions were reported from Donetsk and Poltava regions, among others.

Explosions are said to have taken place in Odessa, Cherkasy and Kryvyi Rih as well.

In Odessa, the power to the city's pumping stations has been cut, resulting in the entire city now being without running water.

- They seem to have focused on knocking out electricity and infrastructure, says SVT's foreign reporter Regina Svedberg Ågren.

Two dead in Zaporizhzhya

Former lieutenant colonel Jörgen Elfving agrees with the analysis.

According to him, the attacks on civilian infrastructure have three purposes:

- Partly to try to break the Ukrainian will to resist, partly to tire out the air defense and partly to create another stream of refugees and put more pressure on the West.

Reports of injuries and deaths have also started coming in.

Reuters writes that two people were killed in the Zaporizhzhya region and that the electricity supply was knocked out in the Sumy region.
