Ukraine braces for potential Russian strikes on anniversary of invasion

Security measures have been implemented across Ukraine in the face of potential Russian attacks on Friday, which marks exactly one year since the start of Moscow's invasion.

School classes have moved online, working from home is being encouraged and security patrols have been stepped up in order to minimize the potential impact of Russian strikes.

Ukrainian schools have been advised to hold classes online "as a precautionary measure," Education Minister Serhiy Shkarlet said in a statement Tuesday.

In Kyiv, a special security protocol has been developed for all educational facilities. Pupils are taking classes online from February 22-24 in the city and the wider Kyiv region, according to the regional military administration.

The decision was made "due to the increased threat of enemy shelling and potential provocative actions on the eve of the one-year anniversary of the full-scale Russian invasion of Ukraine," it said.
