Seoul: South Korea's customs authorities seized nearly 30,000 smuggled guns, knives, and explosives last year, data showed Wednesday. A total of 29,210 items deemed to pose a threat to public safety were seized last year, according to the data submitted by the Korea Customs Service (KCS) to Rep. Park Sung-hoon of the main opposition People Power Party.

According to Yonhap News Agency, the figure is nearly double the comparative figure from the previous year. South Korea prohibits the import of guns, ammunition, and knives with blades that exceed a certain length without authorization from relevant agencies. By type, nail guns, frequently used at construction sites, accounted for the largest share of the seized items at 4,358, followed by knives at 3,213 units. Authorities also seized 21 firearms, 12 firearm parts, and 357 counts of smuggled ammunition.

Concerns over illegal firearms surfaced after a man in his 60s was detained earlier this week for killing his son with a homemade gun. In addition to the two homemade guns he used to shoot his son, nine other guns and 15 explosive devices have been discovered in the suspect's car and his home, the police said earlier.
