Migrant Caravan Map: Where in Mexico Are They and When Will They Reach U.S. Border?

Thousands of Central American asylum seekers determined to make it to the U.S. border have continued their arduous journey north this week, despite the Trump administration's repeated demands that they turn back.

The United Nations has estimated that as many as 7,200 people are making the trek toward the U.S., where the thousands of Central Americans, mostly from Honduras, Guatemala and El Salvador, hope to gain asylum.

The caravan has made significant progress since it began its journey in San Pedro Sula, Honduras, on October 13, making its way through Guatemala and across the Mexico border to Tapachula in Chiapas state and on to nearby Huixtla. But the group is still roughly 1,130 miles from the nearest U.S. border crossing, in McAllen, Texas.

It is unclear how long it will take the caravan to make it to the U.S. border.

By the most direct route, the entire walk from San Pedro Sula to the McAllen border crossing would take approximately 501 hours, according to Google Maps. That means if those traveling with the caravan were to walk 12 hours a day, it would take them approximately 42 days to reach the U.S. border.

Of course, not all members are making the entire journey solely on foot. Some participants are using other means of transport throughout the journey.

In addition, if the caravan's members choose instead to make their way to the Tijuana-San Diego border crossing, where a caravan of Central American migrants arrived in April, the length of their trek could more than double.

While the group now making its way to the U.S. border has seen its numbers swell, growing to more than 7,000 from the approximately 150-plus people it started with, the caravan that made the journey toward the U.S. this past spring saw only about 200 of its 1,200-strong group reach the California border.

The journey toward the U.S. from Honduras is a difficult and dangerous one, with migrants braving long distances on foot in the heat and with limited resources.

Adrian Edwards, a spokesman for the U.N. high commissioner for refugees, said Tuesday in Geneva that the agency is concerned about "the developing humanitarian situation" and warned of fears of "kidnapping and security risks in areas the caravan may venture into."

On Monday, a Honduran man who had joined the caravan died after he fell off a pickup truck and was run over, according to local media reports.

In a separate incident on Sunday morning, five men and one woman from Guatemala died in Chiapas after the vehicle they were riding in overturned several times.

Edwards warned that "in any situation like this it is essential that people have the chance to request asylum and have their international protection needs properly assessed, before any decision on return [or] deportation is made," according to the Associated Press.

United Nations deputy spokesperson Farhan Haq said earlier this week that the International Organization for Migration (IOM) and the U.N. refugee agency had been boosting resources on the ground as migrants made their way north.

The IOM has reported large numbers of people arriving in Mexico, many of whom the organization expects will remain in the country for "an extended period."

Mexican authorities have said they will allow anyone with the proper documentation, including a visa, to enter and move freely within the country. The nation has also said it will work to process anyone wishing to make a request for asylum within Mexico.

Despite its efforts, President Donald Trump has railed against Mexico for failing to stop the caravan from making progress in its journey toward the U.S., calling the situation a "national emergency."

The president has also railed against Central American nations, vowing to cut, or at least significantly reduce, foreign assistance to Honduras, Guatemala and El Salvador after accusing their governments of failing to do enough to prevent citizens from joining the caravan.
