"The perpetrator was an 18-year-old German-Iranian from Munich," police chief Hubertus Andrae told reporters after the massacre.

He had lived in the city "for a while", Mr Andrae said.

"The motive or explanation for this crime is completely unclear," the officer said.

Mr Andrae said the body of the attacker was found about two-and-a-half hours after the shooting began.

His identity was established on the basis of witness statements and closed circuit television.

The body was found in a side street, not far from the shopping mall where much of the shooting happened.

Police say the suspect was not known to authorities and officers were searching his apartment for clues.

Speculation about the gunman's motives ranged from a right-wing extremist attack to an assault inspired by Islamic State.

Some witnesses describe hearing him yelling anti-foreigner insults before opening fire outside the McDonald's restaurant, near to the mall.

In a later conversation with a witness, recorded on a mobile phone, the attacker said he was a German citizen.

Other media reported that the gunman had been bullied for "several years" and was seeking revenge.

US intelligence officials said initial reports from their German counterparts indicated no apparent link between the suspect and Islamic State or other militant groups.

Two others who fled the area quickly were investigated but had "nothing to do with the incident".

Nine people were killed by the gunman.
