Thai authorities have revoked two passports belonging to former Prime Minister Thaksin Shinawatra following an interview he gave in South Korea last week.

The foreign ministry said Wednesday that police advised them that the passports be canceled because the interview could impact Thailand's "security, safety and pride."

In an interview with the South Korea's Chosun Ilbo newspaper that was widely circulated in Thai media, Thaksin suggested that Thailand's Privy Council, which advises the nation's constitutional monarch, had engineered months of anti-government protests that culminated in a May 2014 coup.

Prime Minister Prayuth Chan-ocha, the former army chief, has insisted he staged the coup himself.

Thaksin was ousted in another coup in 2006, and has lived in exile since being convicted on corruption charges in 2008.
