[originaltext] Eleven fishing boat crew who had been left since October in a

Eleven fishing boat crew who had been left since October in a remote area of Russia’s Far East have been rescued after staying nearly three months at an abandoned military base. The eight men and three women sought shelter at the base after their small boats clashed on Oct. 10. Their attempts to repair one of the boats did not succeed and they had to remain at the abandoned base where there were only flour and cooking oil. Other supplies at the base, which was abandoned in 2003, included Christmas decorations, and the crew members put them up on a small tree inside their rooms. But supplies began running low and early this week, five people set off on foot across snowfields. On Friday, after four days of long walking, they reached a working military radio station. The center called rescuers, and helicopters were sent to take the 11 to the regional capital.
