President Park Geun-hye on Tuesday expressed her "deep" condolences to the victims of the recent shooting rampage in Florida and their families, noting that acts of terrorism cannot be justified for any reason.

In a letter to U.S. President Barack Obama, Park said that "South Korea will be with the U.S." in the process of overcoming the shock and sorrow caused by the deadly incident that killed at least 50 people.

"We pray for the souls of the victims, and extend my and our citizens' deep condolences to the bereaved families. We also hope for the quick recovery of the wounded," Park said.

She added, "I express my strong sense of solidarity as to your (Obama's) resolute will not to give in to fears vis-a-vis this incident."

Early Sunday, local time, a gunman opened fire on a crowded gay nightclub in Florida. The attacker was killed in a shootout with police. In addition to at least 50 fatalities, more than 50 have been hospitalized, many of them in critical condition. (Yonhap)
