MADRID (AFP) - The attempt to rescue an injured Spanish climber stranded on a Himalayan mountain in Pakistan since suffering a fall 10 days ago was permanently called off Sunday, his climbing club said. We have decided to suspend the rescue operation given the worsening weather conditions, which prevent this work from continuing, technical difficulties on the terrain, the little chances of finding Oscar alive, climbing club Pena Guara said in a statement. And above all because of the security risk for the climbers on this difficult mountain in bad conditions, it added. Perez, 33, has been stranded some 6,000 metres up Latok II in the Himalayas in northern Pakistan after suffering a fall on August 6 which broke his arm and wrist. A rescue team which included renowned American alpinist Fabrizio Zangrilli had been making its way up the mountain, considered one of the most challenging in the world to climb, but their progress has been slower than expected due to the rough terrain and fatigue. Oscar is not going to be able to hold on much longer, Lorenzo Ortas, the vice-president of Pena Guara which had been coordinating the rescue attempt, told reporters earlier on Sunday. Spanish Prime Minister Jose Luis Rodriguez Zapatero on Thursday called his Pakistani counterpart Yousuf Raza Gilani to request that the operation to rescue Perez be speeded up. Two Spanish climbers died recently in the Himalayas. Luis Maria Barbero, 47, disappeared in July on the slopes of Gasherbrum II which rises to a height of 8,035 metres. Veteran climber Inaki Ochoa de Olza, 40, died in May 2008 as a result of brain injury on the slopes of the 8,091-metres-high Annapurna.
