British prosecutors revealed the details of a terrorist plot to blow up high-profile financial targets — including the World Bank and the International Monetary Fund headquarters in downtown Washington — during a sentencing hearing of a top al-Qaida operative Monday.

Dhiren Barot, 34, pleaded guilty last month to conspiracy to commit mass murder on both sides of the Atlantic in a London court. He was back in the heavily guarded Woolwich Crown Court to admit his part in the London plots and in the conspiracies of back-to-back explosions in D.C., New York and New Jersey.
