Chuvashia’s governor, Oleg Nikolayev, said in televised remarks that it wasn’t immediately clear how long it will take to fix the section of the pipeline cut by the explosion.

“I would like to remind you that what was called Novorossiya back in the czarist days — Kharkiv, Luhansk, Donetsk, Kherson, Nikolayev and Odesa — were not part of Ukraine back then,” he said.

Vladimir Nikolayev, deputy head of the regional health department, told Reuters there were still available beds and patients who needed oxygen were getting it.

“I don’t think it will be worse, but it could be the same nest year,” the regional governor, Aisen Nikolayev, told Reuters on the sidelines of an economy forum in the city of Vladivostok last week.
