(Adds statement from airline)

TORONTO, Oct 25 (Reuters) - A British Airways flight from San Francisco was diverted to Vancouver after members of the cabin crew became unwell, the airline said on Tuesday.

CBC News said earlier on its Twitter feed that 25 passengers and crew were sent to local hospitals for smoke inhalation. But one source familiar with the situation, who declined to be identified, said it was not true that there were smoke inhalation issues.

The airline said in a statement that its Vancouver staff had arranged hotel accommodation for affected customers and will book them on alternative flights as soon as possible.
