All of the German Chancellery, which houses the offices of German leader Angela Merkel, has been given the all-clear by police after part of the building was closed when a suspicious package was spotted.

Earlier Wednesday, part of the building was cordoned off.

But police reopened all of it two hours later, after opening five suspicious letters and finding nothing, a spokeman said.

The area was cordoned off at 8:30 a.m. and the alert ended at 10:44 a.m.
