- At least 22 people, including one child, have died in an explosion at a hotel in Havana, Cuba.
- A gas leak is suspected to be the cause of what authorities are labelling an accident.
- Dozens were injured.
A powerful explosion due to a suspected gas leak ripped through a luxury hotel in central Havana, killing at least 22 people Friday, according to official tallies.
Rescuers pulled four bodies out of the rubble in the early evening as they combed through what remained of the prestigious Saratoga Hotel looking for survivors.
At least one woman with whom rescuers made contact was alive in the debris, officials said, adding they believed more survivors were still trapped and that a canine squad was searching them out.
Cuba's president attributed the massive blast to a gas leak.
"It was neither a bomb nor an attack, it was an unfortunate accident," said Miguel Diaz-Canel, who arrived at the scene an hour after the blast, accompanied by the prime minister and National Assembly president.
"Compatriots and friends around the world. #Havana is in shock today," he tweeted.
The latest death toll of 22, which includes at least one child, was announced on television news after a day in which ambulances and paramedics raced through the center of Cuba's historic capital.
Both the health ministry and the Cuban presidency said dozens had been injured but cited different numbers, ranging from 50 to 65 people.
The first four floors of the establishment, which were closed to guests while being renovated, were gutted in the late-morning blast that sent a cloud of dust and smoke billowing into the air.
The explosion also tore off large parts of the facade, blew out windows and destroyed cars parked outside the five-star hotel, which has in the past hosted celebrities such as Madonna, Beyonce, Mick Jagger and Rihanna.
The dome of a nearby Baptist church also collapsed.
Inside the hotel at the time were employees preparing for its post-refurbishment reopening, scheduled for next Tuesday.
Miguel Hernan Estevez, director of the hospital Hermanos Almejeiras, said a two-year-old boy had undergone surgery for a fractured skull.
"So far we have no information that any foreigner was either injured or killed, but... this is preliminary information," added Tourism Minister Juan Carlos Garcia Granda.
Roberto Calzadilla of state company Gaviota, which owns the hotel, said the explosion happened while a gas tank was being refilled.
Ambulances and fire trucks rushed to the scene Friday and police cordoned off the area, dispersing people who swarmed to the hotel near Havana's emblematic National Capitol Building that housed Congress prior to the Cuban revolution.
It is also next to a school, but no pupils were injured, according to the presidency.
Rogelio Garcia, a bicycle taxi driver who was passing the hotel at the time of the blast recounted that "we felt a huge explosion and (saw) a cloud of dust... many people ran out."
"There was a terrible explosion and everything collapsed," said a woman, her face covered in dust, who declined to give her name.
According to the website of the Saratoga Hotel, it is an upmarket establishment with 96 rooms, two bars, two restaurants, a spa and gym.
It was built in 1880 to house shops and converted into a hotel in 1933.
"The United States sends heartfelt condolences to all of those affected by the tragic explosion this morning," said US State Department spokesman Ned Price on Twitter.
Mexico's Foreign Minister Marcelo Ebrard, meanwhile, said President Andres Manuel Lopez Obrador would not cancel a trip to Cuba planned for Sunday.
"Our sympathy goes out to the victims and those affected, as well as to the people of our dear sister nation," Ebrard tweeted.
Condolences also poured in from Bolivia, EU foreign policy chief Josep Borrell and Nicolas Maduro, the president of close Cuban ally Venezuela, who said "the Cuban people have the solidarity and support of all the peoples of the world" and especially Venezuelans.
