New Delhi, May 2 -- Ukrainian forces struck an oil terminal in the Russian Black Sea city of Tuapse, Ukraine's General Staff said on Friday, marking the fourth attack targeting the region's oil infrastructure in just over two weeks.

Explosions and a fire were recorded at the terminal, the statement from the General Staff said. Local officials in Russia said a Ukrainian drone attack sparked the blaze and that no casualties were reported.

The facility had been hit previously on April 16, April 20 and April 28. Regional governor Veniamin Kondratyev said a fire at the city's oil refinery had also been extinguished Thursday, less than 24 hours before the latest strike.

Meanwhile, Russian attacks continued to strike Ukraine.
