The EU should adopt joint rules of the fight against religious extremism that would reduce the threat of terrorist attacks, German activist, writer and human rights campaigner Seyran Ates said in Prague on Monday.
Ates unveiled a European petition for the adoption of legislation for a joint struggle against terrorism.
At least one million signatures must be collected for the European Commission to deal with a petition.
Ates is a moderate Muslim.
Islamist terrorism is one of the most serious threats everywhere in Europe, she said.
