The Syrian newspaper al-Watan, for its part, claimed that the Syrian troops are already located no more than one kilometer from the city center.
Earlier, RIA Novosti quoted a source in the Syrian Army as saying that Palmyra may be completely cleared of the terrorist groups in less than a week.
Syria considers taking Palmyra tactically vital in advancing toward the Daesh stronghold of Raqqa in eastern Syria.
Daesh seized Palmyra, once capital of the Palmyrene Empire and one of the richest cities in antiquity, in May 2015.
Terrorists destroyed a number of culturally and historically irreplaceable UNESCO World Heritage Sites, including the Arch of Triumph, the Temple of Baalshamin and the Temple of Bel.
Jihadists also looted the national museum and Palmyra's famous necropolis.
In March 2016, the Syrian Army, supported by a group of Russian Aerospace Forces in Syria, managed to liberate Palmyra. Russian specialists demined the historic center as well as residential areas of the city.
However, Palmyra was recaptured by Daesh in December 2016, after the government had shifted its focus to retaking Aleppo. The terror group' gains in the historic city prompted the Syrian Army to launch an offensive in January 2017 in order to retake it once again.
At the time, the army was tasked with driving Daesh out of the territory near Palmyra, where a numger of oil fields were located. About 10,000 soldiers took part in the offensive, including Syria's elite special forces unit, the Desert Hawks.
Notably, Daesh managed to recapture the ancient city after about 5,000 terrorists were moved to Palmyra from the cities of Raqqa, Mosul and Deir ez-Zor – something that Syrian President Bashar Assad blamed on the US-led coalition.
In a December 2016 interview with RT, Assad said that it was the US-led coalition which controlled the main routes of approach to Palmyra and that the coalition turned a blind eye to Daesh's redeployment to the city.
"The US-led alliance either ignored Daesh's redeployment or pushed the terrorists to advance on Palmyra. The matter is that Raqqa and Deir ez-Zor are located just a few hundred kilometers away from Palmyra and the jihadists could advance under the supervision of US satellites, US drones and with the assistance of Americans," Assad pointed out.

The information came after an informed source on the ground told Sputnik that the Syrian government troops had secured control over a strategic traffic interchange at the southern entrance to Palmyra.
Last week, the Syrian army liberated a strategic road conjunction three miles away from Palmyra. The area has been used as a bridgehead to free the adjacent heights from militants.
