SUNDAY TIMES WEB DESK: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 travelers — which raised the ire of President Donald Trump — largely gave up and dispersed.

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 mobilizing.

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.
