U.S. authorities fired tear gas into Mexico during the first hours of the new year to repel about 150 migrants who tried to breach the border fence in Tijuana.
An Associated Press photographer saw at least three volleys of gas launched onto the Mexican side of the border near Tijuana's beach that affected the migrants, including women and children, as well as journalists.
Migrants who spoke with AP said they arrived in Tijuana last month with the caravan from Honduras.
The agency said agents saw “toddler sized children'' being passed over concertina wire with difficulty. It said its agents could not assist the children because of the rocks being thrown. The agency said 25 migrants were detained while others crawled back into Mexico through a hole under the fence.
