An oil shale mine in northeastern Estonia has been ablaze for more than a month, and authorities believe it will take another week to extinguish, a newspaper reported. Kodumaa, a newspaper published in Tallinn, the Estonian capital, said Tuesday that 500 miners had to be rescued and no injuries were reported when the fire broke out Nov. 3 at the Estonia Mine near the town of Kohtla-Jarve in this tiny republic on the Baltic Sea. Firefighters sealed sections of the mine with concrete and then poured in 21 million gallons of water to contain the blaze, whose origin was unknown.
