Thousands of people marched in this capital and other Greek cities on Thursday in an ultimately failed effort to dissuade parliament from approving a renewal of the military cooperation agreement with the United States that gives Washington the right to deploy forces to four additional bases.

Answering a call from trade unions, the Greek Communist Party (KKE), and the extra-parliamentary left, protesters also railed against Greece's provision of armaments to Ukraine as part of an "imperialist war" waged on behalf of the US and NATO.
