Pink Floyd co-founder Roger Waters left the band in 1985, and he hasn’t done anything with the other members of Pink Floyd since playing a one-off show with the band at Live 8 in 2005. But Waters is a longtime critic of Israel’s treatment of Palestine. (Last year, he got into a public dispute with Dionne Warwick over the issue.) And along with David Gilmour and Nick Mason, the other two surviving members of the band, he’s issued a joint statement condemning Israel’s treatment of a group of activists who tried to bring humanitarian aid to Gaza.

Earler today, the Israeli navy detained a boat carrying the Women of the Gaza Freedom Flotilla, a group of female activists who were seeking to break the navy’s blockade of the Gaza Strip, bringing humanitarian aid to the people there and increasing international awareness of the blockade. The 13 women on the boat come from different countries, and they include Mairead Maguire, a Nobel Peace Prize laureate from Ireland. The women aboard have been detained, and Israel’s military says they will hold them in custody for 96 hours before deporting them.

Here’s Pink Floyd’s statement about it:

According to the International Business Times, this statement has led to speculation that Waters and Pink Floyd could play another show together, possibly in Palestine. Pink Floyd haven’t played a show since keyboardist Richard Wright died in 2008, and The Endless River, the album they released two years ago, was mostly made up of archival recordings.
