Members of the migrant caravan have taken part in a mass LGBTQ wedding just a few miles away from their new life in America.

Pedro Pastor, from Guatemala, and Erick Alexander Duran, from Honduras, were joyous after celebrating their wedding with other couples in Tijuana, Mexico, just south of the border with California.

But, while Amnesty says there is 'vicious discrimination' against the LGBTQ community in Central America, Donald Trump has pledged to keep the 3,000-strong caravan out of his country.

Before the election Trump called such caravans an 'invasion.'

The happy couple were joined by at least seven others as they were married on their way to build new lives in the USA

In a video obtained by The Telegraph, Duran said: 'We came with them because there is lots of violence, lots of discrimination, lots of poverty.'

Pedro said: 'This is a dream come true because in our countries you don't see this and it's something we have always wanted and today we had the opportunity and are very happy.'

There are a number of states in Mexico where same-sex marriage is legal and those unions must be honoured in every state.

But for most in Central America the possibility for such marriages is out of the question.

While they make their hopeful applications for asylum, thousands of American troops have been deployed at the border.

Around 3,000 people from the first of the caravans have arrived in Tijuana across the border from San Diego, hoping to live the American Dream.

The troops will be hoping to cut off large swathes of vulnerable ground with new defences and direct the inflow to official customs entry points.

On Tuesday, Trump told reporters on his way to Florida: 'Don't worry about the Thanksgiving. These are tough people.

'They know what they're doing and they're great and they've done a great job. You're so worried about the Thanksgiving holiday for them.

'They are so proud to be representing our country on the border where if you look at what's happening, Mexico, the people from Tijuana are saying, wow these are tough people. They're fighting us.'

Defense Secretary Jim Mattis has declined to publicly discuss cost estimates for the border mission, saying as recently as last week that he had little confidence in the accuracy of figures he had seen.

In its report to Congress, the Pentagon said they would be spending $19 million for personnel, $20 million for transportation of personnel, equipment and supplies, $28 in operating expenses and $5 million for concertina wire and other border barrier materials.

The locals of Tijuana have been protesting the presence of the migrants on their streets, accusing them of living in squalor and causing crime.

Tijuana Mayor Juan Manuel Gastelum has called the migrants' arrival an 'avalanche' that the city is ill-prepared to handle, calculating that they will be in Tijuana for at least six months as they wait to file asylum claims.
