Three climbers from U.S. and Canada are missing on New Zealand's Mount Aoraki, search operations delayed

The articles report on the missing status of three mountaineers, two from the US and one from Canada, who were attempting to summit Mount Cook in New Zealand. The group flew to a hut partway up the mountain on Saturday to begin their ascent, but did not return. Searchers found several climbing-related items belonging to the men, but no sign of them was found. The severe weather conditions are reported to be obstructing the search efforts.
