An explosion early Saturday hit the Ukrainian coal mine where 100 workers died in a methane blast about two weeks ago, the Interfax news agency reported. At least five miners were seriously injured and another 35 were unaccounted for at the Zasyadko mine in Donetsk, the agency said, citing an unnamed official in the State Industrial Safety Committee. Twenty other miners were brought to the surface Saturday the agency reported. The Nov. 18 blast at Zasyadko was the worst coal-mining disaster in Ukraine's post-Soviet history.
