The death toll of a massive explosion at a luxury hotel in Havana, Cuba climbed to 30 on Sunday as rescuers continued searching for possible survivors following the tragedy.

Cuban officials confirmed the latest number, according to Associated Press. Cuba's Health Ministry noted that the fatalities included four minors, a pregnant woman, and a Spanish tourist, Al Jazeera reported.

On the other hand, at least 84 people were injured in the Havana hotel explosion, including the partner of the Spanish tourist. At least 24 people remained hospitalized, and some were in critical condition.

A representative of Grupo de Turismo Gaviota SA, the owner of the Hotel Saratoga in Havana, said at least 13 of their crews were missing.

The said five-star hotel, which exploded on Friday, was built at the end of the 19th century and became the most important hotel in Havana in the 1930s. The Hotel Saratoga has 96 rooms since its reopening in 2005.

Governor Reinaldo Garcia Zapata on Saturday evening said at least 19 families reported that their loved ones were missing and that rescue efforts would continue.

The Hotel Saratoga had been closed for business due to renovation work in recent days. Reports claimed that many of the explosion's victims were construction workers or hotel employees preparing for its reopening, which should have been next week. 

Several nearby structures were also affected by the Havana hotel explosion. Reports claimed that Marti Theater and the Calvary Baptist Church were damaged.

The church said on its Facebook page that its building suffered "significant structural damage," citing several collapsed or cracked walls and columns. The church also claimed that the ceiling of their building also collapsed. But the church added that no church workers had been hurt.
