KYIV, Ukraine • Russia on Tuesday claimed to have taken control of 97% of one of the two provinces that make up Ukraine’s Donbas, bringing the Kremlin closer to its goal of fully capturing the eastern industrial heartland of coal mines and factories.

Russian Defense Minister Sergei Shoigu said Moscow’s forces hold nearly all of Luhansk province. And it appears that Russia occupies roughly half of Donetsk province, according to Ukrainian officials and military analysts.

After abandoning its bungled attempt to storm Kyiv two months ago, Russia declared that taking the entire Donbas is its main objective. Moscow-backed separatists have been battling Ukrainian government forces in the Donbas since 2014, and the region has borne the brunt of the Russian onslaught in recent weeks.

Early in the war, Russian troops also took control of the Kherson region and a large part of the Zaporizhzhia region, both in the south. Russian officials and their local appointees have talked about plans for those regions to either declare their independence or be folded into Russia.

But in what might be the latest instance of anti-Russian sabotage inside Ukraine, Russian state media said Tuesday that an explosion at a cafe in the city of Kherson wounded four people. Tass called the apparent bombing in the Russian-occupied city a “terror act.”

Before the Feb. 24 invasion, Ukrainian officials said Russia controlled about 7% of the country, including the Crimean Peninsula, which Russia annexed in 2014, and areas held by the separatists in Donetsk and Luhansk. Last week, Ukrainian President Volodymyr Zelensky said Russian forces hold 20% of the country.

While Russia has superior firepower, the Ukrainian defenders are entrenched and have shown the ability to counterattack.

While insisting on Ukraine’s need to defeat Russia on the battlefield, Zelenskyy said at a Financial Times conference Tuesday that he is still open to peace talks with Russian President Vladimir Putin. But a former U.S. intelligence officer said the time isn’t right.

“You’re not going to get to the negotiating table until neither side feels they have an advantage that they could push,” said Andrea Kendall-Taylor of the Washington-based Center for a New American Security.

The Russians “think they will be able to take the whole of the Donbas and then might use that as the opportunity to call for negotiations,” Kendall-Taylor said at an online seminar .
