BBC Global News Director, Peter Horrocks, has issued the following statement.
The BBC is very concerned by the continued campaign of the Turkish authorities to discredit the BBC and intimidate its journalists.
A large number of threatening messages have been sent to one of our reporters, who was named and attacked on social media by the Mayor of Ankara for her coverage of the current protests.
The BBC and all its journalists are committed to providing impartial and independent journalism. It is unacceptable for our journalists to be directly targeted in this way. There are established procedures for making comments and complaints about BBC output and we call on the Turkish authorities to use these proper channels.
