KYIV, April 10 (Reuters) - Ukraine has made significant progress restoring the damaged Druzhba oil pipeline and will complete the repairs in spring, President Volodymyr Zelenskiy said, amid a bitter row with Hungary over the disruption to supplies of Russian oil.

The request has allegedly come from both political and military sources.

After reaching pacts with Saudi Arabia, Qatar and the UAE, Zelenskyy said similar agreements were in the works with Oman, Kuwait and Bahrain.

The Ukrainian military has stepped up attacks on Russia’s energy infrastructure, as Moscow benefits from higher crude oil prices and some sanctions relief.

President Volodymyr Zelenskiy said the spring and summer months would be difficult for Ukraine as it would face pressure on the battlefield and also diplomatically to end the war. Zelenskiy ‌said Ukraine's partners had asked Kyiv to reduce its strikes on Russia's oil sector as global prices ‌surged due to the Iran war and escalating tensions in the Middle East.

Hungary will gradually cut off gas supplies to Ukraine until Russian oil deliveries resume through the Druzhba pipeline, Prime Minister Viktor Orbán said on Wednesday. The transit of natural gas through Hungary plays a key role in fulfilling the energy needs of Ukraine,
