Classes resumed in Venezuela’s schools on Wednesday after two major national blackouts left frustrated parents struggling to entertain their children and forced the education ministry to extend the school year.

Two major nationwide power outages led the government to cancel classes across the country. President Nicolas Maduro said earlier this week that classes would resume on Wednesday. Classes at primary schools, high schools and universities were suspended for a week each at the beginning and end of March in the face of prolonged power outages.

As a result of the blackouts, the water pumping and telecommunications systems were also paralysed. The resumption of services has been uneven for the member of the Organisation of the Petroleum Exporting Countries, with cities such as San Cristobal, Valencia and Maracay still reporting intermittent supply of electricity.

In Maracay, about 120 kilometres southwest of Caracas, parents said some schools had few teachers.With at least 6.4 million students enrolled in public schools and 1.2 million in private institutes, the Ministry of Education has not reported how many effectively returned to their activities on Wednesday.
