A federal court in the United States has agreed to extradite Tahawwur Rana, a Canadian businessman of Pakistani-origin, to India.
Rana is sought by India for his involvement in the 2008 Mumbai terror attacks.
California District Court Judge Jacqueline Chooljian has approved the Indian government's request for Rana's extradition.
Rana was arrested in the US on an extradition request by India for his role in the 2008 Mumbai terror attacks, which killed over 160 people, including six Americans.
India has charged Rana with offenses including conspiracy to commit terrorist acts, waging war, murder and forgery.
Rana was convicted in Chicago in 2011 of providing material support to the Pakistan-based terror group Lashkar-e-Taiba, which planned the Mumbai terror attacks.
India's National Investigation Agency (NIA) is probing his role in the 26/11 attacks carried out by Pakistan-based Lashkar-e-Taiba terrorists in 2008.
Extradition is the formal process of surrendering a person from one state to another.
