US claims Ukrainian forces are reclaiming ground from Russians

With the American military suggesting that the Ukrainian forces have started making gains against Russian forces the situation in Mariupol continues to generate concern - the Ukrainian authorities say 100,000 people are trying to flee the city.

As sanctions against Russia begin to bite, there are concerns that Moscow could retaliate by launching cyber attacks on western businesses - the message is that companies should update their cyber protection and remain alert.

And reports from newly-occupied areas of Ukraine indicate that Russian forces have lists of people they want to arrest.
