>> An uncertain end to an arduous month long journey, as about 150 Central Americans from a so-called caravan of migrants in Mexico were camped out on Monday at the US border. Some are trapped inside a port of entry between the two countries as officials barred them from stepping foot on US soil.
At one point, numbering over a thousand, the group who say they're fleeing violence and persecution from El Salvador, Honduras, and Guatemala rode buses, hitchhiked and even walked toward the US border, traveling together for safety. Some tried to report to US border authorities to make asylum claims, but officials said the facility is full.
About 50 spent the night outside the port of entry, while a hundred more rolled out towels and blankets to sleep on concrete in the Mexican Square. Reuters, Delphine Schrank has been traveling with the group, and documented the moment when the caravan reached the border.>> Here we are, hundreds of people looking to the US border.
This is it, this is a big moment, the people on both sides of the border have been waiting for on this side. It's been over a month that migrants have been tracking this way. And they made it finally, and now, come what may, they're gonna hand themselves over and ask for asylum.
>> But they may not get the chance. US President Donald Trump wants them stopped on the Mexican side, and on Monday, used their arrival to call for more border security.>> We are a nation of laws, we have to have borders. We don't have borders, we don't have a country.
>> But those who made the long treacherous journey say, they're just desperate.>>
> I can say that Donald Trump has no heart, but maybe God will help him see his heart a little bit, seeing so many children.>> On Sunday, supporters of the caravan rallied near the barrier between the countries, with some scaling and sitting on the wall.
The migrants say death threats from local gangs, the murder of family members, retaliatory rape, and political persecution back home prompted them to flee. American attorneys told the group, asylum seekers could face detention, long periods of forced separation from their families, and deportation if their claims were rejected.
