The fence will span 30 kilometers (19 miles) along Israel's border with Jordan
The goal is to protect a future airport, and control "illegal migrants and terrorists."
Israel began construction of a fence along its border with Jordan on Sunday, Prime Minister Benjamin Netanyahu announced at a weekly cabinet meeting.
“Today, we are starting to build a fence on our eastern border,” he said Sunday.
“In the first stage, we will build it from Timna to Eilat in order to protect the airport being built there, and we will continue the fence up to the Golan Heights, where we have already built a strong security fence.”
“To the extent that it is possible we will encompass Israel’s borders with a security fence and barriers that will allow us to control our borders,” Netanyahu said.
“We will not allow Israel to be flooded with illegal migrants and terrorists.”
