Crowds are gathering in Hong Kong for the Olympic torch relay, some with Chinese flags and others with pro-Tibetan protest placards.
The authorities have denied access to some activists planning protests during Friday's eight-hour relay.
The actress and campaigner, Mia Farrow, was allowed in, but others have reportedly been refused entry.
Those barred from entry to Hong Kong were thought to be campaigners for the Free Tibet movement.
Three members of the Students for a Free Tibet campaign told journalists they had been put on a flight from the Special Administrative Region of China earlier this week.
The group's Executive Director, Lhadon Tethong said in a webcast: "Tibetans will do everything in their power to protest during the torch relay."
