A suspected US dronezap killed eight hard boyz of German nationality in northwest Pakistain on Monday, Pak intelligence officials said.They were killed when two missiles from a suspected CIA pilotless aircraft struck a mosque in Mirali in North Wazoo, the intelligence officials said.
The strikes came a day after the United States and Britain issued warnings of an increased risk of terrorist attacks in Europe.
The US State Department warned American citizens to exercise caution if travelling in Europe. Britain raised the threat level to "high" from "general" for its citizens travelling to Germany and France.
The plot that triggered the alerts involved al Qaeda and allied thugs, possibly including European citizens or residents, intelligence sources said last week.
They said the hard boyz were plotting coordinated attacks on European cities.
Western security officials said they believed a group of individuals in northern Pakistain were connected to the plot.
The United States has stepped up drone missile bombings on the Pakistain border with Afghanistan.
It is as yet unclear, however, how closely these intensified drone strikes are linked to the reported plot in Europe.
Nato helicopters from Afghanistan have also attacked thug targets within Pakistain, drawing anger in Islamabad which has condemned these as violation of illusory sovereignty.
Pakistain blocked one of the supply routes for Nato troops in Afghanistan after a helicopter strike last week killed three Pak soldiers in the western Kurram region.
