German police question more than 100 witnesses in Munich shootout

German police investigating the suspected attempted terror attack outside the Israeli consulate in Munich have interviewed around 100 witnesses, a police spokesman said on Monday.

The special police commission looking into the attack has not yet found any further evidence to support the "working hypothesis" that the 18-year-old shooter was motivated by Islamism or anti-Semitism, the spokesman for Bavaria's State Criminal Police Office (BLKA) said.

The approximately 100 officers investigating the attack are hoping to gain further insights from the analysis of the Austrian suspect's cell phone.

The device had apparently been damaged during the exchange of fire with the police, but could be accessed. However, the BLKA spokesman said it was still unclear how much data could still be recovered.

The shooter was killed in an exchange of fire with police.

According to the police, the 18-year-old suspect fired nine shots with a Swiss military carbine in the centre of Munich on Thursday - including at the Israeli consulate general and the nearby Munich Documentation Center for the History of National Socialism, known as the nsdoku.

Investigators in Munich believe the shooting was part of a planned terrorist attack, partly because of the location near the consulate and because it occurred on the anniversary of the 1972 Olympic bombing, a terror attack staged by Palestinian militants in which 11 members of the Israeli Olympic team were killed.

Findings by the Austrian police indicated that the 18-year-old could have been radicalized by Islamists.
