After stringing two rows of concertina wire atop the border fence in Nogales starting on Election Day 2018, military troops returned the first week of February 2019 to add up to four more coils, covering the barrier top to bottom in some areas.
A school bus rolls past the concertina wire-covered fence at East International and Nelson streets on Monday morning, Feb. 4, 2019.
This section of fence on the east side of the city over the Tricky Wash was painted white last year to help the Border Patrol better spot fence-climbers. Seen in this photo from Feb. 7, three rows of concertina wire had been added to the barrier.
The Army had previously strung two rows of wire at the top of the border fence at East International and Nelson streets in downtown Nogales. Now there are six.
Concertina wire covers the border fence from top to bottom in this photo taken Feb. 6, 2019 on the west side of Nogales. A barrier stands between the wire and the road for part of this stretch, but not all.
