In recent months and backed by Russian air force, the Syrian government has restored control of over 60 percent of previously rebel-held territory across the country.
It said the army had taken control of al-Haara hill on the second day of an offensive to take back the last parts of southwest Syria in Quneitra province that are in rebel hands and are close to the border with Israel.
The Britain-based Syrian Observatory for Human Rights said government forces fired more than 800 missiles at an area between northern Daraa and the Quneitra countryside, about 4 kilometers, or 2.5 miles, from the frontier with the Israeli-occupied Golan Heights.
Almost three weeks of bombardment saw beleaguered rebels agree with Russian Federation earlier this month to hand over Daraa province, before reaching a similar deal for its capital this week. The evacuees' first stop is the government-controlled city of Aleppo.
They say the intensity of the bombardment has forced rebels in many towns to sign surrender deals that offer safe passage to those who want to move to other opposition areas after handing over their weapons, while enlisting those who stay into the military.
President Donald Trump's top security adviser on Sunday appeared to walk back a promise by the White House to withdraw USA troops from Syria, saying that the United States would remain in Syria so long as "Iranian menace" continues to threaten the Middle East.
The agreement also stated that Syrian army troops would not enter the city unless they were on their way to fight a nearby Islamic State pocket.
Dozens of Syrian refugees approached the Israeli border, many waving white flags, apparently seeking sanctuary as the Syrian army continues to battle with rebels.
Syrian state media says deal reportedly reached over Quneitra

He said regime forces had ousted rebels from Al-Tiha in a military advance, while opposition forces in Al-Hara had agreed a surrender deal. It had reportedly insisted to southern rebels such transfers were not on the table for them, but seems to have ultimately relented.
The government fully regaining Daraa will be a significant blow to the opposition. An HTS ambush then left 12 regime forces dead, Abdel Rahman said.
Syria and Israel fought two wars over their shared border, in 1967 and 1973, with Israel occupying the Golan Heights in the Quneitra province in the former confrontation.
The Observatory said the suspected Russian strikes were the first in the area in over a year, when Russia, the United States, and Jordan agreed a ceasefire deal for parts of the south.
Following his meeting with Putin, Netanyahu appeared to significantly soften his rhetoric towards Assad, whom he has previously branded a "butcher" for his regime's part in an eight-year civil war that has claimed the lives of some 350,000 people and driven millions from their homes.
Quneitra borders the Golan Heights, which has been on high alert since hostilities ramped up in the south almost a month ago.
