South Korean media report possible attack on cargo ship in Strait of Hormuz

South Korean officials were working to verify "information that a South Korean vessel may have been attacked" Monday in the Strait of Hormuz, the country's state-owned Yonhap news agency reported.

The Korea Herald newspaper reported that a South Korean-flagged cargo ship was hit by an "external impact" in the strait Monday, citing South Korean officials, but that it was unclear whether it was a targeted attack or possibly a sea mine.

Yonhap said the foreign ministry in Seoul was aware of the reports, and that it had no confirmation of any South Korean casualties in the incident. 

The Reuters news agency, citing an unnamed spokesperson with the Seoul-based shipping firm HMM, said a fire had been reported on a bulk carrier owned by the company, but that the cause remained unclear. Reuters said the incident involved an explosion in the vessel's engine room.
