Police in Kazakhstan have detained several activists from the Antiheptyl movement, known for its opposition to the launches of Russian Proton-M rockets from Kazakh soil.
The name of the movement is taken from the name of the highly toxic fuel used by the rockets.
About 15 activists staged their protest in front of the presidential office in Astana on April 28.
They placed their written demands to President Nursultan Nazarbaev in a mailbox in front of the building and said they were expressing their opposition to the April 28 launch of a Proton-M rocket from the Baikonur space center in Kazakhstan.
The protesters then unfolded placards saying "No to censorship!", "No to Eurasian Union!", and "Long live Crimea!"
Police dispersed the rally, detaining at least nine of the participants.
