German Chancellor Angela Merkel will leave out the opening of the G20 summit in Argentina after her aircraft was pressured to land shortly after leaving Berlin.
Her administrative center says Mrs Merkel and delegates made a secure, however unscheduled, landing in Cologne after the airplane advanced a technical downside.
The aircraft turned back while it was over the Netherlands, Germany’s dpa information agency says.
Reports say Mrs Merkel will travel on to Buenos Aires on Friday.
No details were given concerning the technical problem.
