When Danish media flashed images of the suspected Copenhagen gunman, Julie recognized her "nice and very smart" former classmate Omar El-Hussein, a good Samaritan who a year ago rushed to her aid.

"I am deeply moved and shocked," the 20-year-old told AFP in a telephone interview from Copenhagen.

Two men were charged in Copenhagen on Monday with helping the gunman who killed two people in twin weekend attacks that have stoked renewed fears of Islamist and anti-Semitic violence in Europe.

Flags were flying at half-mast across Denmark after the shootings that stunned one of the world's most peaceful nations.

Copenhagen police said Sunday they believe a man shot dead by officers was responsible for two fatal attacks that shocked the normally peaceful Danish capital.

The killings, coming little more than a month after bloody Islamist attacks in Paris that left 17 people dead, were described by Danish Prime Minister Helle Thorning-Schmidt as "a cynical act of terror".

A gunman killed at least one person and wounded three police officers after opening fire Saturday on a cultural center in Copenhagen as it was hosting a debate on Islam and free speech.

Swedish artist Lars Vilks -- the author of controversial Prophet Mohammed cartoons that sparked worldwide protests in 2007 -- was among those at the debate targeted by the gunman, who fled the scene after a shootout with police.

A Jewish school in Copenhagen had its windows smashed and anti-Jewish graffiti referring to the conflict in Gaza spray-painted on its walls, the school said on Friday.

"We know that a political message has been written on the walls but we don't know who is responsible," Jan Hansen, headmaster of Carolineskolen, told Agence France-Presse.

The hunt was on Tuesday for a couple of amorous Danish fans pictured having sex on the football pitch where their team had just played out a tedious 0-0 draw.

A photograph of the daring pair, who remain unidentified, has gone viral on the internet.

Traffic in Denmark's capital Copenhagen was in chaos Thursday as some 30,000 demonstrators marched on parliament from four different points to complain about a teacher lockout by schools that has left 800,000 pupils without classes.

"What is going on is just not reasonable," 27-year-old Kamille Soerensen told Agence France Presse.

Diners who forked out for a top-notch meal in a Danish restaurant dubbed the world's best eatery got more than they bargained for when dozens came down with a nasty case of food poisoning.

The two-Michelin-star Noma restaurant in Copenhagen prides itself on dishes like pike perch and cabbages or wild duck and pear but in February its delights left 63 punters and some staff members vomiting or suffering from diarrhea, health officials said Friday.

Israeli and Jewish officials in Denmark on Wednesday warned Jews to avoid openly wearing religious symbols and dress when moving about Copenhagen amid rising anti-Israeli sentiment.

"We advise Israelis who come to Denmark and want to go to the synagogue to wait to don their skull caps until they enter the building and not to wear them in the street, irrespective of whether the areas they are visiting are seen as being safe," Israel's ambassador to Denmark, Arthur Avnon, told AFP.

A Danish court on Monday found four men guilty of "terrorism" over a plot to kill the staff of a newspaper that first published controversial cartoons of the Prophet Mohammed.

The three Swedish nationals and one Tunisian living in Sweden had pleaded not guilty to the terrorism charges, but a district court found all four "guilty of terrorism", chief judge Katrine Eriksen said in the unanimous verdict, which was broadcast live.
