DONETSK, Ukraine, Dec 2 (Reuters) - An explosion on Sunday struck the same coal mine in eastern Ukraine hit by the country's worst mining accident two weeks ago, killing four men and leaving one missing, officials said.

Ukraine's Mining Inspectorate said the four dead were maintenance workers trying to clear the affected section of the Zasyadko mine in Donetsk. Thirty-seven miners were helping the maintenance team and all but one had been taken to the surface.

The 9 p.m. explosion was the second in two days in the area where a methane blast on Nov. 18 killed 101 miners at Zasyadko. (Reporting by Lina Kushch; Writing by Ron Popeski; Editing by Matthew Tostevin)
