Tear gas fired as dozens of migrants try illegal crossing to US

US Border Patrol agents used tear gas and pepper spray to counter rock-throwing migrants when a group of about 150 tried to illegally cross the border from Mexico, leading to 25 arrests, the agency said on Tuesday.

It is the second time since November that border officers have used tear gas during an attempted mass migrant crossing in the San Diego area.

The migrants in the latest case New Year's Eve were among 1,500 who have remained in Tijuana, Mexico, just south of San Diego, California, after a once-5,000-strong caravan of travellers -- which raised the ire of President Donald Trump -- largely gave up and dispersed.

An AFP journalist reported the crowd size at about 100 and observed the group of Central Americans gathering around 8:00 pm Monday night (0400 GMT Tuesday) in an area called Playas de Tijuana on the Pacific coast, often used by migrants as a departure point for attempts to sneak across the border.

There, the border is marked with fencing and a large vertical plate that juts out into the water.

On the other side of it, US border agents were seen mobilising.

As night fell and people on both sides of the frontier prepared to celebrate New Year's Eve, the migrants tried to cross over but at least two smoke bombs were fired and they were ultimately held back.

Those who tried to cross included adult men, women with small children and adolescents.

After that attempt, part of the group stayed near the border and other Central Americans arrived to join them.

Shortly after the New Year began, dozens of migrants stood on a hill from which they could see US border agents, who watched them closely.

When people in this group rushed the border in a second incident, US authorities fired tear gas to disperse them, an AFP photographer observed.

In a statement, US Customs and Border Protection (CBP) said an initial group of 45 migrants turned back towards Mexico, due to the increased presence of Border Patrol agents.

Shortly after, migrants began throwing rocks over the fence at CBP officers.

"Several teenagers, wrapped in heavy jackets, blankets and rubber mats were put over the concertina wire. Border Patrol agents witnessed members of the group attempt to lift toddler-sized children up and over the concertina wire and having difficulty accomplishing the task in a safe manner," CBP said.

It added that agents could not assist the children "due to the large number of rocks being thrown at them."
"The rock throwers were located south of the fence, in an elevated position both above the border fence area and the incursion attempt."
