The move was planned before the fall of the Assad regime, an official said.
Rebel forces in Syria captured the capital Damascus and toppled the regime of President Bashar Assad in a lightning-quick advance across the country.
Meanwhile, the ceasefire in Lebanon is holding despite ongoing Israeli airstrikes on Hezbollah targets, which Israeli officials say are responses to ceasefire violations by the Iranian-backed militant group. The Israel Defense Forces continues its intense airstrike and ground campaigns in Gaza.
Tensions also remain high between Israel and Iran after tit-for-tat long-range strikes in recent months and threats of further military action from both sides.
The Israel Defense Forces operated in Kwdana, Syria, Wednesday slightly beyond the buffer zone.
The IDF says they are there for "strategic reasons" but wouldn't elaborate.

A joint UN convoy consisting of 105 trucks of aid successfully crossed into Gaza and made it to southern Gaza through the Philadelphi Corridor, United Nations Relief and Works Agency for Palestine Refugees in the near east (UNRWA) said in a release Wednesday.
The convoy consisted of enough food for about 200,000 people, UNRWA said.
"The solidarity of the local community was crucial to the success of this mission, as community members provided a safer passage to allow assistance to reach families facing severe food shortages," the UNRWA said in a statement.

The Israel Defense Forces have withdrawn from parts of southern Lebanon. This is the first group of troops pulled back since the ceasefire went into effect.
There are still warnings in place for people to avoid a number of villages near the Israeli-Lebanese border.
"The IDF remains deployed in southern Lebanon and will operate against any threat posed to the State of Israel and its citizens," the IDF said in a statement.
