General Francisco Yanez, high command of Venezuela's air force, said he now recognized opposition leader Juan Guaido as interim head-of-state, according to media reports Saturday. "Wives are sacred. So don't cross that red line".
"This has to do with risk assessment due to Venezuela's current state, not only because of political consequences but due to the impact of sanctions", said Asdrubal Oliveros, director of Ecoanalitica, a consulting firm in Caracas.
This month's protests have received overwhelming support from overseas, with the U.S., Canada and many others already recognizing Guaido as Venezuela's legitimate leader.

A day earlier, thousands led by Guaido protested in various cities, banging pots, blowing whistles and horns, and carrying banners that read: "Armed forces, regain your dignity" and "Maduro usurper".
The government called for a mass rally Thursday to denounce USA sanctions against Venezuela's state-owned oil company that could starve Maduro's government of billions in export revenue but turnout was no more than a few hundred people.
Guaido reappeared Thursday night to address dozens of neighbors and thank them for not letting state security forces intimidate the community.
