The ongoing theft of grain from Ukraine, which legal experts say is a potential war crime, is being carried out by wealthy businessmen and state-owned companies in Russia and Syria, an AP/FRONTLINE investigation has found.

The Aug. 24 attack in the village of Chaplyne was one of the deadliest in months on Ukraine's extensive railway system and came as the country was celebrating its independence day.

In a war awash in atrocities, the deadly March 11 attack on a nursing home near the Ukrainian village of Stara Krasnyanka stood out for its cruelty. But a new United Nations report has found Ukraine’s armed forces share the blame for what happened, effectively making the building a target.

AP journalists in Ukraine have seen the deadly results of Russian strikes on civilian targets first hand. FRONTLINE and The Associated Press are gathering, verifying and documenting evidence of potential war crimes in Ukraine.
