It was Grenada's first ever Olympic medal and the prime minister felt the achievement was worthy of giving the island Tuesday afternoon off work.
"This is a fantastic achievement," Richard Simon, the prime minister Tillman Thomas's press secretary, told Reuters.
"This has basically given Grenada a sense of presence in the international community that we didn't have before in the context of world athletics."
"It's an early carnival for us. It's going to be a culmination basically of three or four days of celebration for Kirani's involvement in the Olympics. It's a huge party."
All three medals in the 400m went to athletes from the Caribbean islands.
