input: Make use of the article to answer the questions. (CNN) -- A Swedish SWAT team backed by local police arrested four people overnight on suspicion of plotting terror attacks, the Swedish Security Service told CNN Sunday.

The four were held in the city of Gothenburg for "probable cause" of preparing the attacks, the highest level of suspicion in Sweden, said Sara Kvarnstrom, a spokeswoman for the security force.

She refused to say whether the suspects had been under surveillance or if the arrests resulted from a tip-off, saying she could not discussed details on an ongoing investigation.

"Through these arrests we have been able to prevent a situation from occurring," Malena Rembe, head analyst at the Swedish Security Service, told CNN affiliate TV4.

Sweden is not raising its terror threat level -- which is currently at 3, with 5 as the highest -- and there is "no reason for the public to be alarmed," she said.

"These arrests have not changed this threat level," Kvarnstrom added.

An art gallery in central Gothenburg was evacuated shortly before midnight local time, police said, but declined to say whether it was connected to the arrests.

A party was going on at the Roda Sten gallery at the time, with about 500 people attending the inauguration of an arts festival, according an interview with a witness in Goteborgs Posten, a local newspaper.

The police cordon was removed at 6 a.m. local time, said Ulf Edberg, a spokesman for Gothenburg police.

input: Make use of the article to answer the questions. (CNN) -- Some long-time Cuba watchers expressed skepticism Tuesday over a report by a former Mexican foreign minister that Communist leader Raul Castro removed two top-ranking officials earlier this month because they were plotting to overthrow him with the support of Venezuelan President Hugo Chavez.

Fidel Castro, beset by illness, ceded power to his younger brother, Raul, pictured, last year.

Jorge G. Castaneda, who served as Mexico's foreign minister from 2000 - 2003, wrote in the March 23 issue of Newsweek, which became public Saturday, that Deputy Prime Minister Carlos Lage Davila and Foreign Minister Felipe Perez Roque were concerned that Raul Castro would make concessions that would betray the 50-year-old Cuban Revolution.

"For at least a month or so, Lage, Perez Roque and others were apparently involved in a conspiracy, betrayal, coup or whatever term one prefers, to overthrow or displace Raul from his position," Castaneda wrote. "In this endeavor, they recruited -- or were recruited by -- Venezuela's Hugo Chavez, who in turn tried to enlist the support of other Latin American leaders, starting with Leonel Fernandez of the Dominican Republic, who refused to get involved."

The Venezuelan Embassy in Washington did not answer a verbal and written request for comment.

The Dominican Republic Embassy in Washington did not answer telephones calls at various numbers.

Robert Pastor, who served as a Latin America National Security adviser for President Jimmy Carter in the late 1970s, returned Saturday from a weeklong visit to Cuba.

Pastor said he wrote Castaneda a letter upon his return expressing his disbelief in Castaneda's contentions. 1. Who is Raul Castro?
