Manchurian Candidate

Assume you are the head of the Secret Service and the President is about to arrive in Europe, where he will spend Monday in Lisbon, Tuesday in Madrid, Wednesday in Rome, Thursday in Prague and Friday in Paris. But just before he departs on Sunday night, you received intelligence from a source that an assassin plans to attempt to assassinate the President on one of those five days in one of those five cities. You further are told that you will not know which day or which city before the President arrives in that city on that day.

Assuming the information is accurate, can any of these cities be logically ruled out as the possible place of the attack? If so, which one(s) are safe for the President to visit?
