(CNN) -- Germany is scaling back increased security measures put in place last November, but the interior minister said Tuesday the move doesn't mean the terrorist threat has completely subsided.
The measures, including a stronger visible police presence across the country, were announced on November 17 in response to what Interior Minister Thomas de Maiziere then called concrete evidence of a possible planned terrorist attack in Germany.
On Tuesday, de Maiziere said Germany would reduce visible security measures such as the stepped-up police presence, but continue with other less visible actions. He specified the changes did not signify an "all clear" for Germany.
According to de Maiziere, the November ramp-up was in response to an attack on air freight traffic in October organized in Yemen, as well as evidence of plans for a terrorist attack in Germany.
Now, he said, European Union and German task forces had developed specific security measures to deal with the threat from Yemen, and the specific threat of an attack in Germany no longer exists.
Continued undercover investigation will be as intensive as in the past, but publicly visible measures no longer were needed, de Maiziere said.
However, he said the increased security measures could return at any time based on the threat level.
