WASHINGTON (APP) - Several people involved in the plotting of terrorist attacks aimed at Europe have been identified and targeted, said Pakistans ambassador to the United States Hussain Haqqani. I think that several people who were involved in the plotting have been targeted, and the others are certainly on the radar of US, Pakistani and European intelligence services, Haqqani told ABC news channel in an interview. Meanwhile, the US media including CNN and ABC reported European and US officials first learned of the current terror threat over the summer following the capture of a suspected German terrorist of Afghan descent, Ahmed Siddiqui, in Afghanistan, who had allegedly been getting training in Pakistani tribal areas. According to a law enforcement official, among the possible targets in the suspected European terror plot are pre-security areas in at least five major European airports, the ABC said. Authorities believe terror teams are preparing to mount a commando like attack featuring small units and small firearms. The State Department issued a highly unusual Travel Alert Sunday for potential terrorist attacks in Europe, saying US citizens are reminded of the potential for terrorists to attack public transportation systems and other tourist infrastructure. Authorities fear that is a repeat of the 1985 attack on the Rome and Vienna airports, when Palestinian extremists threw grenades and opened fire on travellers waiting at ticket counters injuring 140 and killing 19 including a small child.
