Geneva police have increased a deployment at the Swiss city's airport and are conducting a sweep of identity papers and other checks after receiving a tip-off in connection with an investigation in neighboring France.

Police spokesman Sylvain Guillaume-Gentil says the enhanced measures are not linked to the hostage-taking and killing of a priest at a church in Normandy on Tuesday, but would not comment further.
