Mrs Obama and daughter enjoy Spain
Tight security is surrounding Michelle Obama and her nine-year-old daughter Sasha as they spend a summer break in Spain.
President Barack Obama, who has just turned 49, and elder daughter Malia did not make the trip to Marbella.
The White House said Mrs Obama was accompanied by family friends but did not identify them.
The first lady, who is staying at the Hotel Villa Padierna, will also pay an official visit on Sunday to King Juan Carlos and Queen Sofia at their summer home on Mallorca.
