MAGDEBURG, Germany — (AP) — Mourners laid flowers near the scene of the deadly Christmas market attack on Monday as investigators puzzled over the motive of the suspect and fears swirled that the rampage could deepen divisions in German society.

The Johanniskirche, a church a short walk from the scene of the attack, has become a central place of mourning since the suspect drove a car into the busy market on Friday evening, killing five people. A carpet of flowers now covers the broad sidewalk in front of the church.

Prosecutors said the number of injured has risen to as many as 235 as more people have reported to hospitals and doctors, but it's possible there was some double-counting.

Authorities have identified the suspect as a Saudi doctor who arrived in Germany in 2006 and had received permanent residency. They say he does not fit the usual profile of perpetrators of extremist attacks. The man described himself as an ex-Muslim who was highly critical of Islam and in many posts on social media expressed support for the far-right.

“The Magdeburg perpetrator had repeatedly attracted attention by threatening crimes. There were also warnings about him but, according to what is known so far, his political statements were so confused that none of the security authorities' patterns fitted him," Justice Minister Volker Wissing was quoted as telling the Funke newspaper group.

He said Germany may have to “draw consequences for our security architecture” and that a serious debate about that will be needed, “but it's still too early for that" as facts and questions remain open.

The country's vice chancellor voiced fears that the attack will fuel online misinformation ahead of a national election expected in late February. He urged people to "take time for the truth" and said: "Don't let yourselves be infected by hatred."

“There is still a lot we don't know and a lot is unexplained, including the exact motive,” Robert Habeck said in a video posted Sunday. “All the same, I fear that the distrust that was immediately propagated on the net against Muslims, foreigners and people with a history of immigration will entrench itself deeper in society”

On Sunday night, police in the port city of Bremerhaven said they detained a man who threatened crimes at a Christmas market there in a TikTok video. German news agency dpa reported that he had said he would stab any people of Arabic appearance there on Christmas Day.
