Packed together in the tightest of cabins, with little air to breathe and no space at all in which to move, the migrants in this picture show just how far some will go to try to sneak into America.

Mexican police found the 513 agonisingly squashed together in two trucks just outside Tuxtla Gutierrez, Chiapas – an eye-watering 18-hour-drive away from the nearest US border.

They were caught when the trucks sped through a vehicle scanner at a police checkpoint. After the astonishing X-ray image came up on screens, police gave chase, finding 240 people in one truck and 273 crammed into the other.

The 513 migrants, originally from a range of countries, including Guatemala, Ecuador, Japan, China, India and Nepal, were ‘travelling in inhuman conditions,’ according to officials.

They are currently being given aid and food while four people have been arrested on suspicion of smuggling.

The shocking picture comes just one week after President Obama was heckled in El Paso, Texas, after claiming border controls between the U.S. and Mexico had never been more stringent.

He boasted that fewer arrests of illegal immigrants showed that ‘far fewer people are attempting to cross the border illegally’.

‘Even as we have stepped up patrols, apprehensions along the border have been cut by nearly 40 per cent from two years ago,’ he said.

But increasingly shocking examples of migrants attempting to flee their countries and illegally enter the U.S. have emerged over the past few years.

THE 2,000 MILE BORDER AND THE MILLIONS WHO HAVE GOT THROUGH

  • There are an estimated 11 million undocumented immigrants in the United States.
  • The southern border with Mexico spans almost 2,000 miles, with fences being built along one-third, or approximately 670 miles
  • Nearly seven million Mexicans are living illegally in the United States, it is thought
  • About 300,000 Mexicans come to settle permanently in the United States each year, half of whom are undocumented
  • 78 per cent of Mexican immigrants live in just four states, with nearly half living in California alone
  • The Border Patrol now has 20,000 agents – more than twice as many as there were in 2004, according to President Obama

Earlier this year, two Mexicans were caught inside the U.S. after using a 4mph underwater dive scooter to dodge the border fence.

Unfortunately for the two men, aged 38 and 16,they were spotted by a U.S. Border Patrol helicopter crew – still clutching the scooters – as they walked along Imperial Beach near San Diego,  California.

Last August, Mexican police made the gruesome discovery of 72 murdered migrants from Central and South America in northeastern Tamaulipas state.

Two years ago, eight illegal immigrants ‘stacked like wood’ in the back of a sports-utility vehicle were killed when the driver lost control on a remote southeastern Arizona highway.

At least 27 men and women, all illegal immigrants from El Salvador, Guatemala, Honduras and Ecuador were in the vehicle travelling about four miles east of Sonoita when the vehicle rolled shortly before midnight, sending the migrants flying out the car and onto the road.

Mexican lawmakers last month unanimously approved a law to ‘strengthen the protection and security’ of migrants amid widespread abuse by smugglers.

Rights groups have long criticized Mexico for failing to protect tens of thousands of migrants, mainly from Central America, trying to cross the vast country to illegally enter the U.S. each year.
