As he was turned away, demonstrators clashed with soldiers in the capital, when they gathered to mourn a man killed on Sunday.

Manuel Zelaya's plane was forced to turn away as it approached Tegucigalpa airport because of obstacles placed on the runway.

The pilots circled the airport and decided not to risk a crash.

The former president instead headed for El Salvador, vowing to try again to return to power in a country where all branches of government are lined up against him.

US Secretary of State Hillary Rodham Clinton plans to meet Zelaya on Tuesday as the Obama administration weighs responses to his removal from office.

The meeting will be the US administration's highest-level contact with Zelaya since he was overthrown eight days ago.

Zelaya was in Nicaragua on Monday after a late Sunday news conference in El Salvador in which he urged world leaders to step up efforts to return him to power.

About two-thousand people demonstrated peacefully on Monday near the presidential palace.

They have been marching to protest the overthrowal of Zelaya since he was ousted.

On Sunday afternoon, clashes broke out between police and soldiers and the huge crowd of Zelaya supporters which surrounded Tegucigalpa's international airport ahead of his attempt to return to the country.

A 19-year-old male demonstrator was fatally shot as people tried to break through a security fence. At least 30 people were treated for injuries.
