RFE/RL Ukrainian Service journalist Maryan Kushnir suffered a concussion during a Russian rocket attack on Ukrainian forces outside of Kyiv in the early hours of March 11.
Kushnir, who was embedded with the Ukrainian troops, reported that the attack occurred at about 3 a.m. in the town of Baryshivka, about 35 kilometers east of the capital.
There were an unspecified number of other casualties, he said, but no one was killed. Local emergency workers and military medics provided assistance.
Kushnir has worked for RFE/RL since 2015 and has been covering the war with Russia since Moscow attacked Ukraine on February 24.
Fighting in the Kyiv area has grown increasingly intense in recent days as Russian forces seek to surround the city in the face of stubborn resistance.
New satellite pictures appeared to indicate that a 64-kilometer-long military convoy outside Kyiv has spread into towns and forests near the capital, with towed howitzers nearby in for an assault on the city. Armored units were observed in towns near the Antonov Airport north of the city.
The Ukrainian armed forces' General Staff said in a statement that Russian troops were advancing toward Kyiv from the northwest and east.
Kyiv Mayor Vitali Klitschko said about 2 million people had left the city and its environs.
