DUBAI, United Arab Emirates (AP) — Israel has begun a construction project along the so-called Alpha Line that separates the Israeli-occupied Golan Heights from Syria, apparently laying asphalt for a road right along the frontier, satellite photos analyzed by The Associated Press show.

Israeli troops have entered the demilitarized zone during the work, the United Nations confirmed to the AP, a violation of the cease-fire rules governing the area.

The work, which earlier satellite photos show began in earnest in late September, follows the completion by the Israeli military of new roadways and what appears to be a buffer zone along the Gaza Strip’s frontier with Israel.

The Israel military also has begun demolishing villages in Lebanon, where United Nations peacekeepers have come under fire.

So far, there has been no major violence along the Alpha Line, which delineates the demilitarized zone between Syria and Israeli-occupied territory that U.N. peacekeepers have patrolled since 1974.
