The head of technology giant Apple believes privacy is a "basic human right" and no government or private company should be able to access personal information, he said in an interview.
Tim Cook, CEO of the US firm, also said invading people's privacy would not solve the issue of terrorism and would punish the "99.999% of people who are good".

A major police operation will be in place today for the first demonstration in Britain by the controversial anti-Islam group Pegida UK.
Opponents of the group are also rallying in Newcastle city centre, on what will be a busy day for Northumbria Police as it coincides with a Premier League football match.
Pegida organisers have pledged on Facebook that it is a peaceful organisation and not affiliated with right-wing extremists.

George Galloway MP and comedian Russell Brand have backed the counter demonstrators, who come under the banner Newcastle Unites.
It's not known how many people will support the first Pegida rally, although more than 800 people have indicated on Facebook that they will attend.
