US swimmer Diana Nyad attempts to swim from Cuba to Florida

US endurance swimmer Diana Nyad is again trying to become the first person to swim from the Cuban capital, Havana, to Florida without a shark cage.

Her last attempt, a year ago, was hampered by rough seas and jellyfish stings.

The 64-year-old says this will be her fifth and last try to cross the 166km-wide (103 mile-wide) Florida Straits.

Sarah Rainsford reports from Havana.
