School is out and all non-essential work places ordered closed until Thursday after the island’s power grid collapsed.

Cuba has repeatedly failed to bring its electrical grid back up as a result of fuel shortages and deteriorating infrastructure, threatening a social explosion.

Following three days of nationwide blackouts caused by the collapse of Cuba’s electrical system, power was restored to most of Havana on Monday, after Cuban authorities gave up efforts to restore the entire grid for now and opted to try to hook up individual regions around the country.
