Ukrainian authorities are investigating senior military officials in two separate cases of suspected corruption, officials said on Thursday, part of a crackdown on wrongdoing before talks with European Union leaders.
The EU has made addressing corruption a requirement for Ukraine joining the 27-member bloc, a process that takes years.
The two sides are due to meet in the Ukrainian capital Kyiv on Friday, a symbolic trip by EU leaders meant to highlight support for Ukraine as the first anniversary of Russia's Feb. 24, 2022, invasion nears.
