(Reuters) - Ukrainian troops are suffering high losses because Western arms are arriving too slowly to equip the armed forces properly, President Volodymyr Zelenskiy told CNN in an interview aired on Sunday.

Russia has been gaining ground in parts of eastern Ukraine including around Pokrovsk. Capture of the transport hub could enable Moscow to open new lines of attack.

Zelenskiy said the situation in the east was “very tough”, adding that half of Ukraine’s brigades there were not equipped.
