Barack Obama makes rare visit to Puerto Rico

US President Barack Obama is making a rare visit to Puerto Rico, marking the first official trip to the island by a sitting US president since 1961.

The visit is being seen by some as an indirect bid for the votes of Puerto Ricans in the swing-state of Florida during next year's presidential poll.
The 3.8 million residents of the US Caribbean territory are US citizens but cannot vote for the president.
During his stay, Mr Obama will attend a Democratic National Committee event.
The president visited the island in 2008 during his campaign for the Democratic nomination, promising to return if elected president.
"Although my hair is a little greyer than during my first visit, I am glad to be able to keep that promise to the people of Puerto Rico," Mr Obama said as he greeted a crowd gathered in an aircraft hanger.
The president is scheduled to meet Puerto Rico's governor on Tuesday to discuss the political status of the territory.
Mr Obama told the crowd on Tuesday that when Puerto Rico had made a "clear decision" on their future political status, "my administration will stand by you".
The Obama administration has asked Puerto Rico to hold two referendums, the first on whether the territory should be independent or part of the US.
A second referendum would then ask Puerto Ricans if they would prefer the island to be independent, a US state, a free association or a commonwealth.

Targeting voters
 
On Tuesday, Mr Obama also spoke briefly about the impact the economic crisis had on Puerto Rico, saying Puerto Ricans and Americans on the mainland shared the same concerns about the economy.
The BBC's Julian Miglierini in San Juan says many people there believe the visit is aimed at courting mainland America's Puerto Rican electorate - and Hispanic voters in general - as they could hold the key to Mr Obama's re-election in 2012.
The president has called for broad reform of the US immigration system, an issue affecting many Hispanics with ties to the 11 million US illegal immigrants.
Meanwhile, roughly 20 pro-independence demonstrators held an all-night vigil in San Juan ahead of the president's visit, calling for the release of three Puerto Rican nationalists imprisoned in the US.
