Climate activist Greta Thunberg was among dozens of protesters detained on October 5 for blocking a road in the Belgian capital during a demonstration against fossil fuel subsidies, Euractiv reported.

An AFP journalist saw the prominent Swedish woman, who has previously been detained for civil disobedience at protests in various countries, being taken away by police after she refused to leave the sit-in protest.

Thunberg, 21, was part of a smaller group of demonstrators who broke away from a march organized by the United for Climate Justice movement that began outside the European Parliament.

The rally called on the European Union to stop subsidizing fossil fuels in order to reach the ambitious goal of making the continent carbon neutral by 2050.

“This will not happen without an immediate end to fossil fuel subsidies,” climate activists, scientists and economists wrote in an open letter to EU leaders.

“Until these necessary changes happen, people will continue to take to the streets to make our voices heard and hold you accountable,” they note.

A little earlier, Danish police detained Thunberg at a Copenhagen protest against the war in Gaza and the Israeli occupation of the West Bank. Thunberg was later released from custody.

Six people were detained at Copenhagen University after about 20 people blocked the entrance to the building and three went inside, a police spokesman said, without commenting on the specific detainees.

Widely known for her campaign to stop man-made climate change, Thunberg has increasingly taken up the Palestinian cause and said in May that such protests “should be everywhere.”
