What's your question on safety issues in public spaces?

Berlin is the latest city that has suffered a "terrorist attack" as a man driving a lorry ploughed into people at a German Christmas market, killing 12.

This follows a similar attack in July when a driver of a lorry killed 86 people in Nice, France.

What can be done to stop attacks in the future?

Should there be more safety measures put in place to protect the public?

If so, how can they be enforced effectively?
