Bahraini activists protest royal visit to London

Bahraini activists are protesting outside the Savoy Hotel in central London, where they believe Prince Nasser bin Hamad al-Khalifa is staying on a visit to the UK.

Nasser, son of Bahrain's king, recently had his immunity from prosecution removed, after it was alleged he tortured political prisoners in the Gulf State.

It is unclear if UK authorities have granted Prince Nasser special mission status, which would mean police are unable to execute a warrant for his arrest - that's if a warrant has been issued.
