TBILISI, Georgia — Rescue workers in the Georgian capital were still searching today for more than 20 people and an undetermined number of potentially dangerous animals that are missing after severe flooding ravaged the city’s zoo and left at least 12 people dead.

Tbilisi zoo director Zurab Gurielidze said that none of the people who died was killed by the zoo animals set free in the flooding. Three zoo employees drowned.

Among the animals that fled the flooded zoo were lions, tigers, bears, wolves, a hippopotamus and one jaguar. Some, including the hippopotamus, were tranquilized and returned to the zoo. Others were shot by police, while others remain missing.

Zoo spokeswoman Khatia Basilashvili said three lions, three tigers and two jaguars were killed either in the flood or when on the loose, while the fate of five lions, three tigers and one jaguar was not yet known.

The flooding also killed about 60 homeless dogs when the waters inundated a shelter near the zoo, shelter staff said.
