Jamaican teens and preteens compete in the island's track championships at the National Stadium in the capital, Kingston.
When it comes to sprinting, Jamaica reigns supreme.
At the Beijing Olympics in 2008, a Jamaican man — Usain Bolt — and a woman — Shelly-Ann Fraser-Pryce — took home the golds in the 100-meter race, and at this summer's London games, they're hoping to do it again.

In this photograph of a courtroom sketch, Khalid Sheikh Mohammed, charged with orchestrating the Sept. 11 attacks, attends a court hearing at Guantanamo in 2008. He's expected to appear in a military court Saturday.
Khalid Sheikh Mohammed and four other men charged in the Sept. 11 attacks were supposed to be tried six years ago in a military tribunal created by the Bush administration.

Since then, there has been an effort to make sure the trials at Guantanamo are credible, with both Congress and the Supreme Court weighing in.
