LIMA, Jan. 26 (Xinhua) -- Peru decided to withdraw its ambassador to Honduras, Jorge Alejandro Raffo, in response to Honduran President Xiomara Castro's support for Peru's embattled former president Pedro Castillo, the Foreign Affairs Ministry said Thursday.

Castro has said that a "coup d'etat" in Peru had ousted Castillo from office and called for his "immediate release," said the ministry on Twitter.

Castro's comments constitute an "unacceptable interference in internal affairs," said the ministry, adding relations with Honduras will be maintained indefinitely "at the level of charge d'affaires."

Castillo was impeached by Peru's Congress for alleged "permanent moral incapacity" and arrested shortly afterward, sparking waves of protests around the country.
