State media said the army was fanning out along the border areas with Jordan and tightening the noose on terrorists, Reuters reported.
The return of Daraa to Syrian government's complete control would deal a big psychological blow to the terrorists and opposition groups.
On Saturday, Syrian troops captured the Nassib district, the main border crossing with Jordan after the militants announced they had reached an agreement with Russian mediators to end the violence in the southern province of Daraa and surrender the crossing.
Taking back the Nassib crossing paves the way for the Syrian president to reopen a trade artery vital to his hopes of reviving the Syrian economy and starting to rebuild government-held areas.
Syrian forces next target in the southwest appears to be Quneitra province at the frontier with the Israeli-occupied Golan Heights, where fighting between militants and Syrian forces escalated on Friday.
