Puerto Rico Gov. Ricardo Rosselló Nevares declared a state of morning after yesterday's military plane crash, which killed nine airmen from the Puerto Rico Air National Guard.

"Our prayers for the family and friends of these nine Puerto Ricans. In their honor, the flags will fly at half-staff for nine days," said Rossello.

The names of the victims will not be disclosed until family members are notified. The National Guard of Puerto Rico will release the names at a later time.
