LONDON — European security officials said a terror plot to wage a Mumbai-style shooting spree in Britain, France and Germany is still a threat and authorities were monitoring sites in Pakistan where the threat originated.
Intelligence agents intercepted the threat two weeks ago, prompting American forces to increase drone missile strikes against al-Qaida targets in Pakistan.
A British government official said the plot was considered to be in its embryonic stage, and that terror threat levels had not been raised in the U.K.
European officials have warned of an increased possibility in low-budget attacks that require relatively little planning — unlike the Sept. 11 terror attacks in 2001.
Officials gave no other details of the plot, but said the group talked of shooting sprees starting first in Britain, and then in France and Germany.
