SEOUL, Oct 5 (Reuters) - A South Korean military transport aircraft returned 97 citizens and family members from Lebanon on Saturday as Middle East tensions rise, the foreign ministry said.

A KC-330 aircraft left Beirut on Friday afternoon with the evacuees, who include Lebanese family members, and arrived at a military airfield on the south of Seoul, the ministry said.

President Yoon Suk Yeol on Wednesday ordered military aircraft to be deployed to evacuate South Korean citizens from parts of the Middle East as conflict escalates between Israel and Hezbollah, as well as the armed group's backer, Iran.

South Korea's defence ministry said it flew a C130J transport plane as backup, which is capable of operating on shorter runways and under fire, as a precaution, and sent 39 military personnel, including mechanics and diplomats.

The government will take further actions to ensure the safety of its citizens, the foreign ministry said without elaborating.

South Korean diplomats stationed in Lebanon remained in the country, Yonhap news agency reported.
