美国官员周一暂时关闭了世界上最繁忙的过境点之一，以便在中美洲移民大军到达之际建起混凝土隔离墙和带刺铁丝网。
位于墨西哥蒂华纳和加利福尼亚州圣地亚哥之间的过境点关闭，使大量墨西哥人无法为了工作进入美国，也给到墨西哥旅游后回家的美国公民造成交通阻塞。
设立的隔离墙显然是出于对大量人员也许会试图闯过边境进入美国的担忧而采取的预防措施。
来自中美洲各地的移民大军中已有大约3,000人来到蒂华纳，预计这个星期陆续还会有数千人抵达。
蒂华纳的数百名当地人对这些移民报以敌意，对他们呼喊“离开这里！”和“回家去！”
一些人呼应美国总统特朗普的观点，称这些中美洲移民是罪犯，他们成群结伙前来是“入侵”。
特朗普周日在推特上说，美国“没有为这种入侵做好准备，也不会容忍它。他们已经给墨西哥带来犯罪和巨大问题。回家吧。”
但其中一些移民表示人们认为他们是危险人群感到不解，声称他们从洪都拉斯前来美国是为了逃脱暴力和帮派。
U.S. officials briefly shut down one of the world’s busiest border crossings Monday to set up concrete blocks and barbed wire as Central American migrants arrive.
The closure of the crossing between Tijuana, Mexico, and San Diego, California, kept a large number of Mexicans from entering the U.S. where there are jobs.
It also caused a massive traffic backup for U.S. citizens trying to get back home after visiting Mexico.
The barriers are an apparent precaution against fears that a large number of people may try to rush the border to get into the U.S.
About 3,000 migrants from the various Central American caravans are already in Tijuana and thousands more are expected throughout the week.
They have gotten a hostile reception from hundreds of locals in Tijuana, who greeted the migrants with cries of “get out” and “go home.”
Some echoed President Donald Trump’s rhetoric, calling the Central Americans criminals and the caravan an “invasion.”
Trump tweeted Sunday that the U.S. is “ill-prepared for this invasion and will not stand for it. They are causing crime and big problems in Mexico. Go home.”
But some of the migrants are puzzled by fears they are dangerous, saying they fled Honduras for the U.S. to escape violence and gangs.
