Ukraine’s attacks on Russian oil infrastructure climbed to the highest monthly level since December, cutting the neighboring nation’s refinery runs to multi-year lows.

There were at least 21 Ukrainian strikes on Russia’s refineries, assets at sea — including export terminals — and oil pipeline infrastructure in April, according to data compiled by Bloomberg based on public statements from both countries.
