In April, a similar incident occurred in Venezuela's Nueva Esparta state. One person was killed and two other people were injured after about 60 prisoners escaped from a local jail. The inmates, who seized arms from a guardhouse, attacked and injured two prison guards, local media reported.

Venezuela has been suffering from a severe political crisis since late January when US-backed opposition leader Guaido proclaimed himself interim president in a bid to oust Venezuelan President Nicolas Maduro from power. Maduro has accused Guaido of being a US puppet working with Washington to orchestrate a coup so the United States can control Venezuela’s natural resources.

Russia, China, Cuba, Bolivia, Turkey and a number of other countries have voiced their support for constitutionally-elected Maduro as the only legitimate president of Venezuela.
