Malek Merabek, who's brother was killed in the Charlie Hebdo attacks, has called for unity across France -- echoing concern of heightened anti-Islamic sentiment in the country.   

Policeman Ahmed Merabet was shot dead on the ground at point-blank range, outside the offices of Charlie Hebdo.

His brother, Malek, said he is devastated by the tragic events, and was now calling for unity across the country. 

"Don't tar everybody with the same brush, don't burn mosques -- or synagogues. You are attacking people. It won't bring our dead back and it won't appease the families."

France is home to the European Union's biggest Muslims community.

Attempting to curb anti-Islamic sentiment, German Chancellor Angela Merkel said it was important to see the difference between radical Islamists and Islam. 

"To be well informed about Islam is certainly helpful. The best thing is to talk to the Muslim population, that's why I welcome the idea that the Muslim communities have had of inviting others for vigils. I think that's a very important step."

French President Francois Hollande has also called for unity, saying "it's our best weapon" against further violence.
