A hacker attack has again paralyzed several state websites in Ukraine.
Several pages of the Ministry of Defense stopped working on Tuesday.
The military suspected an overload due to a large number of requests, a so-called DDoS attack.
In addition, two large state-owned banks were temporarily affected.
Card payments no longer worked.
As recently as January, dozens of websites from ministries and institutions were shut down;
Kiev suspected a Russian attack behind it.
The hacking came amid high tensions in the conflict with Russia.
According to Western media reports, Russian troops may be about to invade the former Soviet republic.
But Moscow has rejected this several times.
