Israel has begun a construction project along a demarcation line that separates the Israeli-occupied Golan Heights from Syria, apparently laying asphalt for a road right along the frontier.

The United Nations says Israeli construction along a demilitarised buffer zone with Syria has led to “severe violations” of a 50-year-old ceasefire agreement, which risk increasing tensions along their shared frontier in the occupied Golan Heights.

The work, which UNDOF said began in July, follows the completion by the Israeli military of new roadways and what appears to be a buffer zone along the Gaza Strip’s frontier wit

The UN confirmed that during the construction, the IDF extended into the demilitarized zone in violation of the ceasefire agreement in the area.

Satellite photos show construction along the Alpha Line, which delineates the demilitarised zone between Syria and Israeli-occupied territory.
