BRATISLAVA, Slovakia (AP) — The flow of Russian oil to Slovakia through the Druzhba pipeline that crosses Ukraine has resumed, Slovak Economy Minister Denisa Saková said Thursday.

Hungary and Slovakia have been locked in an escalating feud with Ukraine since Russian oil deliveries to Hungary and Slovakia were halted in January.

Unlike most of the rest of the EU, Hungary and Slovakia still depend on Russia for their energy needs.

The two countries have accused Ukraine of failing to repair a damaged pipeline. Hungary has blocked a massive EU loan to war-wracked Ukraine while Slovakia wouldn't endorse new sanctions against Russia until the supplies resumed.

The flow resumed after three months at 2 a.m. Thursday.
