BERLIN: Police in Germany say they have detained two men suspected of an arson attack against a newspaper that republished the cartoons of French weekly Charlie Hebdo.

The newspaper Hamburger Morgenpost said on its website the overnight arson attack destroyed several files in its archive, but didn't injure anyone.

Hamburg police said it had detained the two young men near the newspaper building.

Spokeswoman Karina Sadowsky didn't give any details about the men and said police were still investigating the incident.

The Hamburg tabloid newspaper published the Charlie Hebdo cartoons the day after the attack against the newspaper in Paris to express its solidarity with the slain journalists. Several other national and local German newspaprs also published the cartoons. They are now getting police protection. Suspected militant held after return from Syria.

German police arrested a suspected supporter of the insurgent group Islamic State (IS) who was recently in Syria and raided his apartment in the state of North Rhine-Westphalia, federal prosecutors said on Sunday.

The 24-year-old suspect, who has German citizenship, was suspected of having joined IS during a stay in Syria from October 2013 until November 2014, a spokeswoman of the federal prosecutor general said.
