The list of targets includes the luxury Hotel Adlon near the Brandenburg Gate, the German capital's central station and its landmark TV tower at Alexanderplatz, US news channel Fox News said on Sunday citing unnamed intelligence officials.
The report came in the wake of a US State Department travel alert urging Americans to be vigilant against the potential for terror attacks in Europe. The Notre Dame Cathedral and Eiffel Tower in Paris are also allegedly being targeted by terrorists.

The US State Department issued a formal alert on Sunday urging Americans to take precautions in public places and transportation systems when travelling in Europe.

News media in the past week reported that Western intelligence agencies had uncovered an al-Qaida plot to launch attacks in Britain, France, Germany and
the United States.
The chairman of the parliament's interior affairs committee, Wolfgang Bosbach, said there had been "no indication of an attack on a concrete target at a specific
There is "no reason to panic and no reason to fundamentally strengthen security measures," he told Monday's edition of Cologne's Stadt-Anzeiger newspaper.
