BORDER BREACHED: 'Frustrated' Migrants 'Breach' US-Mexico Border

Two small migrant children appeared to be dropped from the Mexico side of the border into the Arizona side by a suspected smuggler, according to surveillance footage provided by the U.S. Customs and Border Protection (CBP) on Monday.

As McAleenan told Fox News, numerous migrants were "lured" to the United States because they were promised entry because of weak laws - even though many of them do not qualify for amnesty.

Thousands of migrants on the Mexico side of the border are living in crowded tent cities in Tijuana after a grueling weeks-long journey through Mexico on foot and hitching rides with the goal of applying for asylum in the U.S.

The President has repeatedly threatened to "completely close" the entire southern border should the crisis escalate.

The move came a week after hundreds of migrants rushed the U.S. border, prompting U.S. Customs and Border Protection and Border Patrol officers to fire tear gas and smoke grenades at the crowd, which included many women and children. He helped the adults over the fence and then was caught on camera dropping a two-year-old and a seven-year-old over the fence to the family below on the US side, Homeland Security said. US Border Patrol agents had the territory between the two barriers heavily covered. "We'll figure out what to do in a couple of days".

The migrants in Tijuana are part of several caravans that traveled through Mexico in an effort to enter the United States, citing issues such as widespread violence and dismal job prospects in their home countries.

One of the children "suffered a facial injury" and was treated on the scene. Associated Press revealed that almost 4,000 migrants, including asylum seekers and refugees, have died or gone missing along the route through Mexico toward the USA border in the past four years. That rule was struck down last month by a federal judge.

Tijuana Mayor Juan Manuel Gastélum said it is costing the city $25,000 per day to feed and house the 7,000 migrants now in the city.

US authorities say they can process up to 100 asylum seekers a day. "That's not fair. How do you think people from Tijuana feel towards those people who are making problems?"
