As regional fears mount over spillover from Syria's civil war, Israel plans to build a fence along its border with the embattled country, CNN reported.

The announcement came during Prime Minister Benjamin Netanyahu's weekly Cabinet address, in which he cited the construction of a 230-kilometer fence along Israel's southern border with Egypt.

"We intend to erect an identical fence, with a few changes based on the actual territory, along the Golan Heights. We know that on other side of our border with Syria today, the Syrian army has moved away, and in its place, global jihad forces have moved in,"Netanyahu said, according to a transcript of his remarks.

"Therefore, we will defend this border against both infiltration and terrorism, just as we are successfully doing on the Sinai border."

Syrian opposition and government sources have reported that the extremist al-Nusra Front, which the United States has designated as a terrorist group with links to al Qaeda in Iraq, has taken part in some of the fighting in Syria.
