A Danish man whose Facebook comments appeared to back the gunman behind the deadly Copenhagen attacks will not face charges of condoning terrorism, a prosecutor said Thursday.

The unidentified man had posted comments including "Je suis Omar" and "We are all Omar" on his Facebook page, referring to Omar El-Hussein, who killed two people in the twin shootings on February 14 and 15.

The gunman who killed two people in twin attacks in Copenhagen nearly a week ago was due to be buried later Friday at a Muslim cemetery despite objections from the Islamic group that owns it.

The group said it had considered denying a request by the parents of 22-year-old Omar El-Hussein -- identified by police as the shooter -- to have him buried in the group's Muslim cemetery, but that its rules did not allow for it.

A drab collection of four-storey buildings in a rough area of Copenhagen has become a potent symbol of Denmark's struggles with integrating Muslims in the wake of last week's attacks.

The Mjoelnerparken neighborhood was the home of 22-year-old Omar El-Hussein, the Danish-born man of Palestinian origin who is believed to have carried out the attacks that killed two people.

Crowds of mourners turned out Wednesday amid high security for the funeral of a Jewish man killed in the Copenhagen shooting spree as questions mounted about whether more could have been done to prevent the attacks.

Dan Uzan, a 37-year-old volunteer security guard, was killed outside Copenhagen's main synagogue in the second of two weekend shootings that sent jitters across Europe.

A Swedish cartoonist believed to have been the target of one of the deadly Copenhagen shootings said Tuesday that Danish police had underestimated the terrorist threat since January's Paris attacks.

"The attacker had good weapons, he had better weapons than the police," Lars Vilks, who has been forced into hiding since the weekend shootings, told AFP.

Denmark's intelligence agency acknowledged Tuesday that the suspected gunman in the deadly Copenhagen shootings had been flagged up by prison authorities as being at risk of radicalization.

But it said there was no evidence that the suspect, identified as a 22-year-old Danish-born man with a history of criminal violence, had been planning attacks.

Tens of thousands of Danes have gathered for a torchlit vigil in Copenhagen to commemorate the victims of two shootings that shocked the nation and heightened fears of a new surge in anti-Semitic violence.

Stunned citizens in what is usually one of the world's most peaceful countries flocked to Monday's rally in a square near the cultural center where the first attack took place. Many held flaming torches aloft, illuminating the chilly winter night.

Germany said Monday it wants Jews to stay and promised to ensure their security following a deadly attack on a Danish synagogue and calls from Israel for European Jews to emigrate. 

Chancellor Angela Merkel said Germany was "glad and also grateful" to have a Jewish community, when asked about Israeli Prime Minister Benjamin Netanyahu's renewed appeal following Sunday's attack in Copenhagen.

Dozens of bouquets of flowers were left Monday at the site in Copenhagen where the suspected gunman behind two fatal shootings at the weekend was killed by police.

An Agence France-Presse reporter saw several people laying flowers outside the building in the inner-city neighborhood of Noerrebro where Omar El-Hussein was shot dead.

Danish Jews on Monday turned down an offer by Israeli Prime Minister Benjamin Netanyahu to emigrate to Israel following a deadly weekend attack on a synagogue in Copenhagen.

"We're very grateful for Netanyahu's concern but having said that, we are Danish -- we're Danish Jews but we're Danish -- and it won't be terror that makes us go to Israel," said a spokesman for the Jewish Community in Denmark, Jeppe Juhl.
