(CNN) -- A South Korean navy ship was sinking in the Yellow Sea near North Korea early Saturday, and the navy was shooting at an unidentified ship toward the north, Korean news agencies reported.
It was initially unclear whether the two incidents were related.
Yonhap News Agency quoted Navy officials saying Friday that a ship carrying 104 crew members was sinking off the Seoul-controlled island of Baengnyeong in a flashpoint area between the Koreas.
The 1,500-ton ship was sinking between 9 and 10 p.m. near the island, but the cause of the incident was not immediately known, officials said.
A rescue operation was under way. There were no immediate reports of casualties, but some sort of explosion occurred in the rear of the ship, officials told Yonhap.
The South Korean government issued a statement saying the reason for the incident remains unclear.
As a result of the report, South Korean government officials held an emergency meeting of ministers handling security-related matters, officials told Yonhap.
South Korea's Korean Broadcasting System said the ship, the Cheonan, was patrolling southwest of the island around 9:45 p.m. when the explosion took place, a military official said.
The official said Navy vessels and helicopters were rescuing crew members, some of whom reportedly jumped into the sea after the blast, the KBS report said.
The official said the Sockcho, another South Korean navy vessel patrolling nearby, fired at unidentified ships north of the area.
