Berlin police say a gasoline bomb was thrown at a parliamentary office building in the capital overnight and they are investigating a possible far-right connection.

Police said in a statement that the projectile was thrown at the facade of the Paul-Loebe-Haus, a modern office building opposite the chancellery, in the early hours of Monday but failed to ignite and caused no damage. They say notes left near the building prompted police to suspect a right-wing extremist motivation but didn't elaborate.

A similar attempted arson attack September at the main Reichstag parliament building, which police at the time also suspected had a far-right background, also failed to cause significant damage.
