North Korea warned South Korea about a maritime search operation it says entered its territorial waters, state news agency KCNA reported, citing a statement from the Korean Central News Agency.
“We don’t care whether the south side conducts any kind of search operation in its territorial waters or not,” North Korea said.
“But we can never overlook any intrusion into our territorial waters and we seriously warn the south side against it”.
“We urge the south side to immediately halt the intrusion across the military demarcation line in the west sea that may lead to escalation of tensions”.
