London, September 14 (RHC)-- Tens of thousands of people marched in London Saturday to demand Britain do more to help refugees. The protest came just before British Prime Minister David Cameron left for Lebanon to visit refugee camps.

Longtime anti-austerity, antiwar lawmaker Jeremy Corbyn spoke at the rally just after he was elected leader of the opposition Labour Party. Corbyn said: "We, as ordinary, decent people, stand up and say to our government: 'Open your minds and open your attitude toward supporting people who are desperate, who need somewhere safe to live, want to contribute to our society, and are human beings just like all of us.’"

Tens of thousands more people rallied across Europe over the weekend to take part in what organizers were calling a "European Day of Action for Refugees." Danish police say as many as 30,000 people had gathered in Copenhagen, shouting "Refugees are welcome."

In Italy, hundreds of people gathered at the Venice waterfront, removed their shoes and marched barefoot, as the Venice Film Festival was underway. Protesters also rallied in Spain, Ireland, Austria, Greece, Finland, Norway, Turkey, France and Iceland.
