The defense ministry on Monday reaffirmed its commitment to swiftly cooperate with the police to carry out President Lee Jae Myung's instruction for a probe into drone incursion allegations made by North Korea. On Saturday, Lee ordered a prompt investigation into alleged drone incursions into the North, warning that such acts would constitute "a grave crime" that threatens peace on the Korean Peninsula and national security if true.
