Domestic and international flights were suspended or delayed for about three hours at Incheon International Airport on Wednesday due to North Korea's resumed trash-carrying balloon campaign, officials said. On Tuesday night, North Korea launched another batch of large balloons carrying trash toward South Korea, marking the sixth such action against the South since late May. Another batch of hundreds of balloons was flown to South Korea's border areas Monday night as well. Due to the North Korean balloons, takeoffs and landings of both domestic and international flights were suspended or delayed at Incheon International Airport from 1:46 a.m. to 4:44 a.m. on Wednesday, the airport operator said. The decision was made due to concerns about potential safety accidents involving balloons possibly being sucked into airplane engines, company officials said. All flights resumed normal operations as of 7 a.m. Source: Yonhap News Agency
