Hamburg supermarket attacker was ‘known Islamist’ with psychological problems
Authorities had not believed that the man, a Palestinian from the United Arab Emirates, posed an imminent threat

Identified as a 26-year-old Palestinian, he arrived in Germany in 2015 from Norway but was due to be deported as his application for asylum was rejected.
Friday’s assault risks reopening a bitter debate over refugees two months before general elections, putting pressure on Chancellor Angela Merkel over her decision to open Germany’s borders in 2015 and let in more than a million asylum seekers.
Merkel expressed her sympathies to victims and their families and vowed that “the violent act must be and will be clarified”.
Investigators were still struggling to determine the exact motive for the assault, which left six people injured.
The suspect “was known as an Islamist but not a jihadist,” said the port city’s interior minister Andy Grote, noting “there are indications of radicalisation”.
