Washington reportedly limits satellite data after minister spoke publicly about suspected facility in North Korea

The US has partly restricted intelligence sharing with South Korea after the country’s unification minister publicly identified a suspected North Korean nuclear site, according to reports in South Korean media.

Chung Dong-young told lawmakers in March that North Korea was operating uranium enrichment facilities in Kusong, a north-western area that had not previously been officially confirmed as a nuclear site alongside the known facilities at Yongbyon and Kangson.

A senior military official told the state-funded Yonhap news agency on Tuesday that Washington had imposed partial restrictions on sharing satellite-gathered intelligence about North Korean technology since early this month, though surveillance of missile activity continued normally and military readiness remained unaffected.

The restrictions followed what South Korean outlets described as multiple protests from US officials, who expressed concern that sensitive information had been disclosed without authorisation.
