HAVANA: Cuba plunged into darkness for the second time in less than a week on Saturday after its national power network failed again, strained by aging infrastructure and a US oil blockade.

As night fell, Havana’s streets were mostly pitch black, with people navigating using phone lights or flashlights, just five days after the previous blackout.

In the touristy old city, some restaurants were able to stay open thanks to generators, with musicians playing music, but the regular blackouts have made life more difficult for Cubans.

“This is becoming unbearable,” Ofelia Oliva, a 64-year-old Havana resident, told AFP.

“It hasn’t even been a week since we experienced a similar situation. It is getting tiresome,” Oliva said as she returned home after giving up on plans to visit her daughter.
