International terrorist Ilich Ramirez Sanchez, better known as "Carlos the Jackal," is expected to testify in the Berlin trial of a German left-wing extremist. French authorities have agreed to transfer Sanchez to Berlin for his testimony under tight security. Sanchez, 54, is currently serving a life sentence in a French prison for murdering two French intelligence agents and an informant. The Venezuelan native was convicted of the murders in 1975 but only captured in Sudan in 1994. Johannes Weinrich, whose trial began on March 5, is accused of plotting a series of bomb attacks in France, Germany and Greece with "Carlos." The blasts left six people dead and more than 150 injured. Weinrich, 55, is already serving a life sentence for a 1983 attack on the French cultural institute in Berlin, which killed one man and injured 23 people.
