Deliveries through the TurkStream are back up to "normal volume", Szijjártó said in a statement issued by his ministry.

Hungary has enough gas in store to cover more than 37% of annual consumption, well over the European average of a little more than 21%, he added.

Szijjártó is in Saint Petersburg to participate at the St Petersburg International Economic Forum. He will meet there with Deputy Prime Minister Denis Manturov and Rosatom head Alexey Likhachev.
