Fusako Shigenobu, who served 20 years for French embassy siege, believed to have masterminded deadly Tel Aviv attack

The founder of one of the most feared terrorist organisations of the 1970s has walked free from a Japanese prison after completing a 20-year sentence for the siege of the French embassy in the Netherlands.

Once described as “the empress of terror”, Fusako Shigenobu founded the Japanese Red Army, a radical leftist group that carried out armed attacks worldwide in support of the Palestinian cause.
