From the Sydney Morning Herald:
German police are staging a manhunt for a Tunisian man after the deadly assault on a Berlin Christmas market on Monday, which left 12 dead and dozens wounded.
The man was in contact with Islamist militants in North Rhine-Westphalia (NRW) and was known to German security agencies, the state's Interior Minister said on Wednesday.
"Security agencies exchanged their findings and information about this person with the Joint Counter-Terrorism Centre in November 2016," NRW Interior Minister Ralf Jaeger told a news conference.
He said the suspect had applied for asylum in Germany and his application was rejected in July. Attempts to deport the man to Tunisia failed as he did not have identification papers, and the Tunisian authorities disputed whether he was their national.
