'Putin has proposed forming a "Eurasian Union" of former Soviet nations'
'Russian police have brutally dispersed an opposition rally in Moscow.
Police spokesman Gennady Bugachyov said 24 people were detained Tuesday.
Riot police broke up the protest outside a subway station minutes after the activists formed a chain and started chanting slogans against Russian Prime Minister Vladimir Putin.
The protesters also tried to unfurl banners criticizing upcoming parliamentary and presidential elections.
The police were seen twisting protesters' arms and forcing them into police vans.
Putin is expected to reclaim the presidency, raising the possibility he could prolong his increasingly authoritarian rule through 2024.'
