Israel boosted security in the Golan Heights on Friday, sending troops and police to the northern region and denying access to non-residents, the military and an AFP photographer said.
The military deployed additional troops, setting up temporary checkpoints to restrict access to the area amid fears that protesters could repeat Sunday demonstrations that saw dozens breach a security fence and enter from Syria.
The demonstrators were among thousands of Palestinians who gathered in the West Bank, Gaza and on Israel's border to mark the founding of the Jewish state, which they mourn as a "nakba" or "catastrophe."
Israeli troops opened fire on demonstrators from Lebanon and Syria as they tried to breach a security fence and enter Israel. Four protesters from Syria were killed along with another 10 from Lebanon. Hundreds were wounded.
A military spokeswoman confirmed that additional security measures had been taken on Friday, traditionally a day of protest in the Muslim world.
"The border fence is a military zone, the approaching of which is forbidden and potentially dangerous," the spokeswoman told AFP.
"The decision to declare a closed military zone in the Golan Heights is made according to real-time situation assessments and will be reconsidered as the situation progresses.
"There's a checkpoint so that people won't cross into the closed military zone, it's a temporary checkpoint that's just for today," she said.
An AFP photographer at the scene said the situation was quiet at midday (0900 GMT), with no sign of protesters gathering on either side of the ceasefire line.
On Thursday, the Israeli military said it planned to close the Erez border crossing with Gaza early on Friday "due to expectations of violent demonstrations in the Gaza Strip in the direction of Erez crossing."
But a spokesman for the crossing told AFP on Friday that the decision was rescinded and the crossing would close at its regular time.
Activists in both Lebanon and Jordan told AFP that there were no plans on Friday to repeat the Nakba Day demonstrations, though several activist groups on Facebook have called for protests in the West Bank and Gaza.
In the Gaza Strip, activists planned protests in Beit Hanun in the north and near Khan Yunis in the centre.
