Washington: Technical problems have forced the Bush administration to retool a high-tech "virtual fence" along the US-Mexico border and will delay the first phase for at least three years, Washington Post reported yesterday.
There are an estimated 12 million illegal immigrants in the United States, many from Mexico.
Immigration is a highly charged topic and a major issue in the campaign for November's US presidential election.
Department of Homeland Security officials and congressional auditors told lawmakers on Wednesday that problems found in the 45km pilot project built near Nogales, Arizona, by Boeing Co will require a change in plans, the Post reported.
Homeland Security Secretary Michael Chertoff had announced on Friday, during a review of border-control efforts, that the so-called Project 28 was finally ready for service in efforts to stop illegal crossings. The $20 million (73.4 million) project of sensor towers and advanced mobile communications was supposed to be completed in mid-2007 but had been delayed by software problems.
The surveillance system was designed to complement a planned 1,130km border fence that has drawn opposition along its route.
Initial deployment
While the Department of Homeland Security took over the high-tech project from Boeing last week, authorities confirmed the initial deployment did not work as planned or meet the needs of the US Border Patrol, the Post said.
The newspaper quoted the department official responsible for border security, Gregory Giddens, as saying: "we ... have delayed our deployment as we work through the issues on Project 28. While there is clear urgency of the mission, we also want to make sure we do this right."
The Post report cited congressional investigators saying that, because of the new troubles, the first phase will not be completed until near the end of the next president's first term.
Republican presidential front-runner Senator John McCain of Arizona is fighting conservative criticism that he has been too soft on illegal immigration.
The Democratic candidates, New York Sen Hillary Clinton and Illinois Sen Barack Obama, accuse the Bush administration of heavy-handed tactics.
