PRAGUE, Sept. 16 - Slovak gas importer SPP reported a 25 percent reduction in gas supplies from Russia via Ukraine on Tuesday, the biggest drop since a decline in deliveries was first reported last week, Reuters reported.

SPP spokesman Peter Bednar said the fall was from what the company had requested from Russia's Gazprom for deliveries for Tuesday.

"SPP today reports an almost 25 percent drop in gas supply," Bednar said in an emailed statement.
