Ecuador's ex-vice president Jorge Glas, imprisoned after a dramatic raid on Mexico's embassy in Quito, has gone on hunger strike after a failed suicide attempt, his friend and former boss Rafael Correa said Wednesday.

Correa, who was Ecuador's president from 2007 to 2017, wrote on X that Glas "is on a hunger strike."

Glas, 54, was returned to prison Tuesday after a short hospital stay that officials said was brought on by his refusal to eat for a 24-hour period.

Correa claimed in his social media post to have received confirmation that "the medical emergency was a suicide attempt" by Glas.

Sonia Vera, one of Glas's lawyers, also said on X that her client was refusing to eat and released a video in which he claimed to have been beaten.

Ecuador's security forces stormed the Mexican embassy in Quito on Friday night -- a rare incursion into what is considered inviolable diplomatic territory -- to arrest Glas, who had been granted asylum by Mexico.

Glas, who had already served time on corruption charges, was the subject of a fresh arrest warrant for allegedly diverting funds intended for reconstruction efforts after a devastating earthquake in 2016.

The embassy intrusion triggered a political storm. Mexico, several other Latin American states, Spain, the European Union, United States and the UN chief condemned it as a violation of the 1961 Vienna Convention governing diplomatic relations.

Mexico, which cut diplomatic relations and pulled its embassy personnel from Ecuador, said it would file a complaint at the International Court of Justice in The Hague.

Glas was vice president from 2013 to 2017 under former leftist president Correa, who is living in exile in Belgium to avoid serving an eight-year corruption sentence in Ecuador.
