Dramatic moment green acid paint is thrown in Putin challenger

A leading foe of Vladimir Putin has claimed the Kremlin ordered a suspected acid attack on him which he fears will lead to him losing the sight of his right eye.
Alexei Navalny was splashed with green paint near his office in Moscow, Russia, but the damage he has suffered leads doctors to believe that a stronger corrosive liquid was added.
The charismatic anti-corruption campaigner - who aims to oust Putin as president - has been warned he could lose his sight.
'The doctor thinks that the brilliant green paint was mixed with something else,' he said. 'I am now applying eye drops every 15 minutes for the third day.'
'I have had injections for two days and we are fighting to keep the eye transparent' - but failure would mean he will lose his sight, he said.
'It is unpleasant, but what can we do with it. This is Russia in 2017 and instead of political debates they pour some acid into your eyes.'
The police have ignored his demand for an investigation into the attack close to his Moscow office, he said.
Blaming the Kremlin, he claimed: 'The attack was organised by the president's administration.'
A group called the National Liberation Movement are behind a succession of green paint attacks on him and other opposition figures.
'They are constantly informed about my movements, hotels, tickets, arrivals and departures,' he said.
'Where I come in and where I go out. Of course, information from databases and CCTV cameras is provided to them by the secret services. They also guarantee that they will be untouchable.
'CCTV cameras won't work - and police won't organise a criminal investigation.'
He alleged that Putin's administration 'financed the whole thing'
'The police hotline received a message that brilliant green was splashed on Alexei Navalny on Leninskaya Sloboda Street,' said a spokesman for the Interior Ministry.
He was taken to hospital where he was diagnosed with 'chemical eye burn by brilliant green antiseptic liquid, and was released after aid was provided to him.'
A female activist with an anti-Putin party is also feared to have almost completely lost her eyesight after a recent acid attack.
Natalia Fedorova was attacked by a male assailant. Her political party Yabloko had demanded a criminal investigation.
