The Latest on a series of attacks in Germany in the past week (all times local):

11:45 a.m.

A German official says a Syrian who blew himself up in southern Germany, wounding 12 people, was to be deported to Bulgaria.

An interior ministry spokesman says Syrians can't be deported directly to Syria because of the situation there.

The spokesman, Tobias Plate, said he could not say "at this moment why the deportation" of the 27-year-old failed asylum seeker didn't happen. It was not clear when he was supposed to be deported.

The man blew himself outside a bar in Ansbach after being turned away from an open-air music festival.

Police say a 21-year-old Syrian asylum seeker who killed a 45-year-old woman with a machete and injured two in southwestern Germany worked together with the victim.

German news agency dpa reported Monday that the attacker said in an interrogation that he worked with the woman in the same restaurant in Reutlingen. It was not immediately clear how well they knew each other.

The asylum seeker, who was arrested right after the attack on Sunday night, was known to police and according to investigators he had psychiatric problems.

He was having an argument with the woman before attacking her about 4:30 p.m. on Sunday. The suspect, whose name was not released, then wounded another woman and a man as he fled.

A hospital treating four people wounded by an ax-and-knife-wielding man who attacked people on a German train last week says two of the victims remain in intensive case.

Wuerzburg's university hospital said in a statement Monday that "the state of health of all patients has stabilized but the risk of complications remains substantial."

It said one of the patients, a tourist from Hong Kong, is still in a medically induced coma.

A fifth person wounded in the attack has been released from hospital.

The 17-year-old attacker was an Afghan asylum-seeker who assaulted the group of Hong Kong tourists on a train near Wuerzburg before jumping off and attacking a woman walking her dog. He was later shot and killed by police.

The Islamic State group claimed responsibility for the attack, though authorities say it appears he acted alone.

The incident last Monday was the first in a series of attacks that have shaken Germany over the past week.

Officials say the man who blew himself up near a music festival in the Bavarian town of Ansbach, wounding 12 others, was known to police for low-level drug offenses.

Regional police spokeswoman Elke Schoenwald says the 27-year-old Syrian man had also twice before attempted suicide.

A team of 30 investigators are interviewing the man's acquaintances and examining evidence collected from his home at a nearby asylum-seeker shelter.

Schoenwald said the unnamed man's asylum application had been rejected a year ago, but he had been given temporary permission to remain in Germany.

An emergency response coordinator says paramedics working at a music festival in Ansbach were quick to react to the blast that killed the attacker and wounded 12 people in the Bavarian town late Sunday.

Dieter Seyerlein said medics were present with several ambulances "and could immediately start with primary care, and thus could give a very exact report on the situation, how big the deployment possibly would become."

He said additional first responders were mobilized within half an hour.

9:30 a.m.

Police say a 27-year-old Syrian blew himself up in the outside seating area of a wine bar near an open-air concert in southern Germany, killing himself and injuring 12 — three of them severely.

Bavaria police said in a statement Monday morning that security staff noticed the man with the backpack near the entrance of the concert site in Ansbach, where some 2,500 people were listening to music bands on Sunday night around 9:45 p.m.

Police spokeswoman Elke Schoenwald said he was refused entry to the concert because he didn't have a ticket. He then sat down on a chair outside the nearby restaurant. According to witness accounts he briefly leaned forward at 10:10 p.m. and then triggered the explosion.

Police on Monday morning raided a nearby asylum shelter where the attacker seems to have lived, according to other residents of the home.
