Could Pink Floyd be planning a reunion concert in support of Palestine?

Well, band member Roger Waters took to Facebook yesterday, posting a message that suggests that it's definitely a possibility.

Waters' post references the recent detention of female activists aboard a boat that attempted to break the Israeli blockade of Gaza, in an effort to deliver aid to the besieged Palestinian area.

This isn't the first time that Waters has expressed his support for Palestine. The rock star has long been vocally opposed to Israeli aggression and has consistently expressed his solidarity with the Palestinian people.

"After visiting Israel in 2005 and the West Bank the following year, I was deeply moved and concerned by what I saw, and determined to add my voice to those searching for an equitable and lawful solution to the problem," Waters wrote in an op-ed for Salon in 2014.

He also expressed his full support of the Boycott, Divestment, and Sanctions (BDS) movement: "I have determined that the BDS approach is one I can fully support."

Speaking of Palestine, Waters told The Independent in February: "This is an ancient, brilliant, artistic and very humane civilization that is being destroyed in front of our eyes."

Earlier this week, Waters also posted a video expressing support for the flotilla heading to Gaza .

In the video, Waters also expressed his support for the fans of the Scottish football team, Celtic, that waived Palestinian flags during a match between the team and an Israeli football club. The Celtic club was fined by the UEFA over the protest, but in response, fans raised more than 130,000 British pounds  ($161,748) for Palestinian charities.
