Children from Central America flood U.S. border--again

The number of Central American children fleeing to United States is booming once again  as security and economic troubles continue to grip El Salvador, Guatemala and Honduras.

The rush of minors across the southwest border became a political firestorm in the summer of 2014, prompting the Obama administration to enact emergency measures to stem the flow and drawing intense scrutiny from critics of the president's immigration policies.

Last year, the efforts seemed to work as the number of unaccompanied minors from those three countries entering the U.S. dropped from nearly 70,000 in 2014 to 39,970.

Now the exodus to the USA is back on the rise. In the first 11 months of the 2016 fiscal year, which ends in September, 54,052 children made the journey.
