The Wednesday declaration comes days after it was announced that the Military will continue installing contra wire along the United States-Mexico border.
As tensions are heating up in Nogales over concertina wire strung up across the border fence, the mayor of Douglas, Arizona, says increased border militarization is making life worse for residents in his city.
Authorities closed the DeConcini Port of Entry near Nogales after a man was shot attempting to run over a border patrol agent on Thursday night.
Nogales, a city of about 20,000 people, is economically reliant on Mexican shoppers and cross-border trade.
"Large bus loads of individuals are being bussed up to the border and we don't have any infrastructure in that area", the official said on the call with reporters. Illegal crossings in that area have dropped steeply in recent years.
