South Korean golfers missing after falling into Nan river

Jun Yong Sung, 68 and Jaseoong Ha, 76, were on a golf cart with their caddie parking on a ferry on the banks of Nan River in Prompiram district when another golf cart carrying two South Korean female golfers bumped into their cart from the rear. 

The impact pushed the first cart into the river. Their Thai caddie managed to swim back ashore but the two Koreans are still missing.
The ferry was about to bring the golfers back to their clubhouse when the accident happened.
