Ukraine's domestic arms manufacturers bristle at the notion the country relies entirely on military aid from the U.S. and Europe. The country's weapons development and production, they say, is robust.

Several large Ukrainian cities were attacked, including the capital, Kyiv, as well as Dnipro, Lviv, Odesa and Kharkiv.

Volodymyr Zelenskyy says he is making an effort to answer any legitimate questions concerning his administration and its conduct during the war in Ukraine.

More than 100 countries ban such weapons because unexploded bomblets can be picked up by civilians, causing injury or death. An announcement is expected Friday.

The fate of the private military company is unclear, especially after it was credited with delivering Russia recent gains in the country's war against Ukraine.
