After serving 20 years in prison for her role in a 1974 embassy siege, the co-founder of the Japanese Red Army militant group has been released.

Before being apprehended in Osaka, Fusako Shigenobu, 76, had eluded capture for decades.

Her once-feared organization had planned to use high-profile terror attacks to spark a global socialist revolution.

They were responsible for a number of kidnappings and hijackings, as well as a deadly attack on an Israeli airport.

Shigenobu, on the other hand, spent time for the 1974 attack on the French embassy in The Hague.

There were three Red Army terrorists that held the ambassador and a number of others hostage for 100 hours.

After France released a Red Army militant, the group went to Syria, ending the siege.

Shigenobu did not take part in the attack, but she was determined to have helped coordinate it by a Japanese court in 2006.

This is why, she was sentenced to 20 years in prison for her role.

While awaiting trial, she disbanded the Japanese Red Army, declaring that she would pursue new fights within the law.

The automobile bombing of a US military club in Italy in 1988 was the group’s last known action.

She apologized for causing “harm to innocent people” in the pursuit of her causes when she was released from prison on Saturday.

She had already expressed grief for the murders of 26 people who were killed in a 1972 attack on Tel Aviv’s Lod Airport.

“It’s half a century ago… but we caused damage to innocent people who were strangers to us by prioritizing our battle, such as by hostage-taking,” she said.
