Pussy Riot are sending a message of solidarity to Hong Kong's pro-democracy protesters from 4,000 miles away in Moscow. To mark the two months since the Umbrella Revolution began, the Russian punk activists are projecting images and words of support on the Lennon Wall in Admiralty, a key protest site in the city. 

Holding umbrellas – the de facto symbol of the country's movement – the five balaclava-clad Pussy Riot members hold a sign saying: "Occupy Hong Kong." Peter Gabriel and South Carolina singer-songwriter Iron and Wine also joined Pussy Riot in sending through images of encouragement and support.

Dubbed StandByYou 2.0, the project is organised by human rights group The Voice Project, Human Rights in China and Stand By You: Add Oil Machine, a campaign group that has been projecting messages of good will and hope onto the wall in downtown Hong Kong. In the past two months, the group have beamed around 30,000 messages were sent to its website from 70 different countries. 

The Voice Project founder Hunter Heaney said: "We want to show the faces of some of the people around the world who so admire what these young people are doing. We wanted to show them that we still stand with them and to help counteract propaganda that they don’t have support out there." 

Hong Kong protesters have faced increasingly hardened opposition to their cause. Triad gang members have allegedly been sent into the protest camps to incite violence, while police have used pepper spray in an attempt to clear out the demonstrators. 

As the movement enters its third month, the government has made no further attempt to engage protest leaders after rejecting their key demand for genuine universal suffrage. Just this week, two of Hong Kong's most prominent student leaders were arrested after police cleared the protest camp in Mong Kok.
