Zetra Olympic Hall in Sarajevo, destroyed by Serb gunners during the Bosnian war, was reopened yesterday.

Less than 100 people attended a small, closed ceremony that featured a few dozen teenagers, dressed all in white, dancing briefly to broadcast music. A big ball symbolizing the Earth was placed in the middle of the hall.

"Today, at this place, where until a few months ago there was nothing but senseless ruins, we are gathered to receive the gifts of Olympic friendship and solidarity," said Bogic Bogicevic, president of the Bosnian Olympic Committee. "Here we witness the victory of good over evil."

The hall was rebuilt with the help of money from the International Olympic Committee, whose president, Juan Antonio Samaranch, turned over the key to Mayor Rasim Gacanovic.

"Today, we celebrate the culmination of our collaborative efforts to rebuild this Olympic Hall, which we hope will contribute to the process of reconstruction of Bosnia and reconciliation between its people," Samaranch said.

The head of the European Union Office in Bosnia, Hansjorg Kretschmer, said, "International sporting events at Zetra will carry a message of peace and understanding around the globe.

"After nearly four years of grim fame as the besieged city in . . . Europe, Sarajevo is again becoming the city of the Winter Olympic Games," he said.

Boxing

Trimmed Trinidad

IBF welterweight champion Felix Trinidad has lost 18 pounds to reach the division limit of 147 pounds for his fight tonight against Colombia's Hugo Pineda.

Trinidad was up to 164 pounds according to his doctor, Roberto Munoz Zayas. He will go into this bout at 146 and is favored to remain undefeated and set up a big-money September date with Oscar De La Hoya.

"I can't lose this fight because it means I would miss my chance to knock out De La Hoya," Trinidad said. "I have to win against Pineda to seek out this other fight."

Hall Ban Upheld

An arbitration panel in Lausanne, Switzerland, upheld the three-month suspension imposed on American swimmer Gary Hall Jr. last year for a positive marijuana test.

Hall, winner of two relay gold medals at the 1996 Atlanta Olympics, allegedly tested positive for marijuana at a meet in Phoenix on May 15, 1998.

FINA, swimming's international governing body, handed Hall a three-month suspension on Nov. 6 of that year. Hall then appealed to the Court of Arbitration for Sport (CAS) in Lausanne.

A three-man CAS panel upheld the ban, saying, "The FINA anti-doping rules constituted a sufficient legal basis to allow the federation to sanction athletes for use of marijuana, including sanctions for out-of-competition tests."

Hall, who lives in Phoenix, won gold medals as part of the U.S. 400-meter freestyle and 400 medley relay teams in Atlanta. He also won silver medals in the 50 and 100 freestyle.

In November, FINA deducted two of the three months already served by Hall during a temporary suspension. That left him with 30 more days to serve through Dec. 12.

Hall won a court order that allowed him to compete in a World Cup meet in Texas on Dec. 2, where he won the 50-meter freestyle.

It was unclear whether yesterday's ruling will annul that victory from the books.
