Tear gas, the international language.
Via Daily Mail:
Migrants faced tear gas once again as they tried to cross the US-Mexico border from Tijuana to San Diego on New Year’s Eve.
Around 100 Central American caravan migrants failed in their attempt to cross the border and enter the US on Monday.
As night fell and people on both sides of the border prepared to celebrate New Year’s Eve, the migrants tried to cross over.
The US Customs and Border Protection (CPB) then hurled two smoke bombs at the migrants, holding them back.
One migrant could be seen with his face covered in treatment after tear gas was thrown at the Mexican side of the fence in Tijuana.
Other photos showed migrants trying to take cover as a thick wall of tear gas surrounded them, or crying out in pain after they were hit by the gas.
