Relatives grieve outside the Yubileynaya mine office, 45 km (28 miles) outside Novokuznetsk, May 24, 2007. The death toll from a methane blast at a Siberian coal mine on Thursday has risen to 35 with three people still missing, a spokeswoman for Russia's Emergencies Ministry said, weeks after 110 miners died in a blast at a neighbouring mine operated by the same company.
