Seven men convicted of taking part in a terrorist plot to detonate explosions including a radioactive "dirty bomb" were sentenced to prison terms Friday.

Mohammed Naveed Bhatti, Junade Feroze, Zia Ul Haq, Abdul Aziz Jalil, Omar Abdur Rehman, Qaisar Shaffi and Nadeem Tarmohamed were convicted of joining a plot led by Dhiren Barot.

Barot, a 34-year-old British convert to Islam, was sentenced to life in prison last year. In May, the Court of Appeal reduced his minimum sentence to 30 years, noting that there was no actual attempt to act on the plot.

Barot was convicted of plotting to bomb several U.S. financial targets, London hotels and train stations, using limousines packed with gas tanks, napalm and nails.
