The first LGBT festival to take place in Busan this weekend is hiking up tensions between pro- and anti-LGBT groups, according to Haeundae Police on Tuesday. The possibility of clashes between the two groups is putting local police on high alert. The festival will start at 10 a.m. Saturday at Haeundae beach. There will also be a parade that begins at 4 p.m. and will go around adjacent areas before ending at Gunam-ro Culture Square, which leads back to the beachfront.
