North Korea has raised its security level over possible assassination attempts against its leader, according to reports.

South Korean Yonhap Television reports the Korean National Intelligence Service (NIS) as saying that “North Korea is raising security levels in anticipation of a possible assassination of Kim Jong-un.”

According to the report, South Korea’s intelligence agency informed lawmakers Tuesday that North Korea had stepped up security measures for its leader, Kim Jong-un, amid concerns about a potential assassination attempt.

The NIS shared its assessment during a parliamentary audit session, according to statements received by Yonhap Television Rep. Lee Seong-kweun of the ruling People Power Party and Rep. Park Sun-won of the main opposition Democratic Party.

The report said the NIS informed lawmakers that North Korea increased security around Kim Jong-un in response to possible assassination threats.

Measures include the deployment of communications jamming vehicles and the introduction of drone detection equipment. The agency also noted an increase in the number of Kim’s public appearances, totaling 110 since the start of the year, an increase of about 60 percent from the previous year.
