Russia cuts off gas supply to Ukraine again

 Russian gas firm Gazprom has confirmed it has halted gas supplies to Ukraine after a breakdown on pricing talks.

It comes a day after Ukraine's state energy firm Naftogaz announced it was suspending gas purchases from Russia.
That announcement came after EU-brokered talks aimed at keeping supplies running for three to six months broke down without agreement.
Gazprom said it halted the supply because Ukraine did not make an "advance payment" for July's delivery.
CEO Alexei Miller said Russia stopped delivering gas to Ukraine at 10:00 local time (07:00 GMT) on Wednesday.

"Gazprom won't deliver gas to Ukraine at any price without prepayment," he was quoted by Russian media as saying.
It is the second time in a year that Russian fuel supplies have stopped running to Ukraine.
Russia cut off gas supplies in June 2014 as the conflict between the government in Kiev and pro-Russian rebels in the east of Ukraine escalated.(s:bbc)
