10. SOUNDBITE: (Spanish) Alberto Nunez Feijoo, president of the region of Galicia:
"July 24 will no longer be the eve of a day of celebration but rather one commemorating one of the saddest days in the history of Galicia, but tragedy brings out the best in people. July 24th, 2013, the day the train derailment took away the lives and dreams of many people, will be also the day on which the Galicians overwhelmed blood donation centres."
Spanish investigators were trying on Thursday to determine why a passenger train jumped the tracks and sent eight cars crashing into each other just before arriving in
the northwestern shrine city of Santiago de Compostela on Wednesday evening.
At least 77 people were killed and more than 140 injured in the accident.
Authorities did not identify any possible causes of the accident on a pronounced curve just outside Santiago de Compostela, but a spokeswoman with Spain's Interior Ministry said on Thursday that the possibility that the derailment was caused by a "terrorist" attack had been ruled out.
She spoke on condition of anonymity because of ministry policy.
It was Spain's deadliest train accident since 1972, when a train collided with a bus in southwestern Spain, killing 86 people and injuring 112.
Prime Minister Mariano Rajoy, who was born in Santiago de Compostela, toured the crash scene on Thursday with rescue workers and then went to a hospital to visit injured passengers.
Officials in the city meanwhile cancelled ceremonies for its annual religious festival that attracts tens of thousands of Christians from around the world.
Alberto Nunez Feijoo, president of the region of Galicia of which Santiago de Compostela is the capital, declared seven days of mourning to honour the victims.
"July 24th will no longer be the eve of a day of celebration but rather one commemorating one of the saddest days in the history of Galicia," said Feijoo.
But he praised those of the region, saying said July 24th was also the day on which "Galicians overwhelmed blood donation centres."
