A Muslim-led demonstration in support of the Paris terror attacks' victims was held in Berlin today (13 January) to promote religious tolerance and freedom of speech.

Called by the Central Council of Muslims in Germany (ZMD), the vigil was attended by German Chancellor Angela Merkel and President Joachim Gauck.

Addressing the crowd, which included government representatives and leaders from Christian and Jewish groups, German President Joachim Gauck said: "We are all Germany.

"We, democrats with our different political, cultural and religious backgrounds -- we, who respect and need each other."

ZMD chairman Ayman A. Mazyek also greeted the crowds and said: "We all mourn. The terrorists have not won and will not win. We are all Germany."

Mazyek urged the crowd to promote a, "society open to world."

Also in attendance were religious leaders, including the President of the Central Council of Jews in Germany and Mayor Michael Müller who urged Berliners to reject Islamaphobia.

Abraham Lehrer, the President of the Central Council of Jews in Germany, praised Lassana Bathily, the Muslim immigrant who protected Jewish shoppers at the kosher supermarket that was attacked last week in Paris.

Holding #JeSuisCharlie and 'Yes to tolerance' signposts, 14,000 demonstrators gathered in front of the Brandenburg Gate in Berlin, reported ARD television.

Announcing the vigil, the Muslim Council and the Turkish Community of Berlin had condemned 'the despicable terror attacks in France in the strongest terms' and stressed that 'there is no justification in Islam for such acts.'
