(CNN) North Korea appears to be expanding work at its nuclear test site to include a second tunnel, a US-based think tank said on Thursday, as South Korean and US officials say North Korea might conduct a nuclear test any day. Preparation work at the Punggye-ri Nuclear Test Facility's Tunnel No. 3 was apparently complete and ready for a possible nuclear test, the Center for Strategic and International Studies said in a report, citing commercial satellite imagery. North Korea conducted six underground nuclear tests at the site from 2006 to 2017. The research group said that for the first time, analysts had spotted new construction activity at the facility's Tunnel No.
