• A gunman opened fire in three locations in Oslo, Norway, on Saturday, killing 2 people and injuring 21.
  • Authorities said they have reason to assume the attack was a hate crime because a gay venue was targeted.
  • A suspect has been arrested, and police said they were investigating it as a terrorist attack.

A man has been arrested and charged with murder, attempted murder, and terrorism after a shooting in Oslo, Norway, left two people dead and 21 injured.

A gunman opened fire at three locations, including popular gay bar London Pub, in the early hours of Saturday morning, authorities said.

The suspect is a 42-year-old Norwegian citizen originally from Iran, with a record of minor crimes, police attorney Christian Hatlo said in a press conference on Saturday, per The New York Times.

Hatlo said the police have reason to assume that the attack was a hate crime because a gay venue was targeted. He added that police were investigating the shooting as a terrorist attack.

"He seems to have had the intention to create fear in the population," Hatlo said.

The shooting took place hours before the city was due to hold its annual Pride parade.

Organizers later said that the parade and other Pride events had been canceled at the advice of the police, The New York Times reported.

"We will soon be proud and visible again, but for now, for today, we will hold our Pride events in our homes," Inger Kristin Haugsevje, the leader of Oslo Pride, said in a statement.

Hatlo said that 10 people were seriously wounded in the attack and 11 had minor injuries, per The New York Times. He said that police seized two weapons, including a fully automatic one.

Norway, where mass shootings are rare, was the site of the 2011 terror attacks when right-wing extremist Anders Breivik killed 77 people.

The country has restrictive gun laws, where gun owners are required to be licensed and take safety classes.

A ban on semiautomatic weapons in Norway took effect last year in response to the 2011 shooting.
