This comes as Trump's blockade of crude oil imports to the Caribbean island has reduced fuel stockpiles to dangerously low levels.

"A total disconnection of the SEN has occurred. The causes are being investigated, and protocols for restoration are being activated," the Energy Ministry said on X around 1400 ET.

Earlier, we reported that Trump is in talks with Cuba and that a deal could be reached soon.

Over the weekend, Cuban President Miguel Díaz-Canel publicly admitted for the first time that Havana was in talks with Washington.

As Aldgra Fredly detailed earlier for The Epoch Times, U.S. President Donald Trump said on March 15 that the United States is in talks with Cuba and expects to reach a deal with the communist-ruled country soon.

Trump told reporters aboard Air Force One that "something will happen with Cuba pretty quickly," and that Washington will decide on Cuba after dealing with the war in Iran.

Trump on Jan. 11 told Cuba to strike a deal after U.S. forces captured Venezuelan leader Nicolás Maduro in a Jan. 3 operation. Cuba has long been a close ally of Maduro's regime and has relied on Venezuela's oil supply for decades.

After Maduro's ouster, interim Venezuelan leader Delcy Rodríguez redirected oil deliveries to the United States.

"Cuba also wants to make a deal, and I think we will pretty soon either make a deal or do whatever we ?have to do," Trump told reporters on March 15. "And so, we're talking ?to Cuba, but we're going to do Iran before Cuba."

On Jan. 29, Trump signed an executive order imposing tariffs on any country that "directly or indirectly provides oil to Cuba," a move that exacerbated fuel shortages in the Caribbean island nation.

In his order, Trump accused the Cuban regime of aligning itself with "hostile countries, transnational terrorist groups, and malign actors," including Russia, China, and Iran, as well as U.S.-designated foreign terrorist groups Hamas and Hezbollah.

Cuban leader Miguel Díaz-Canel Bermúdez said on March 13 that his government has been negotiating with U.S. officials to identify and resolve any bilateral issues between the two nations.

"These conversations have been aimed at seeking solutions, through dialogue, to bilateral differences that exist between the two nations," Bermúdez said, according to a statement posted by Cuban Foreign Minister Bruno Rodríguez Parrilla on social media. "There are international factors that have facilitated these exchanges."
