Long-simmering differences between Native Hawaiians and the military over access to Makua Valley have flared anew, with the Army notifying two prominent groups that they will no longer be allowed access to four sacred sites they've visited in the past.

Malama Makua and Hui Malama say the Army's notice, contained in a June 12 letter, may violate a 2001 court order guaranteeing cultural access to many sites in the valley, including the four sites they can no longer enter.
