Quoting a "senior Pakistani Taliban operative", BBC Urdu reported that the base was set up with the assistance of ex-Afghan fighters of Middle Eastern origin who have moved to Syria in recent years.
At least 12 "experts" in warfare and information technology had gone to Syria in the last two months, he said.
Their presence in the country is likely to have a sectarian motive, BBC report said adding Taliban factions feel that Sunni Muslims, who constitute a majority in Syria, are being oppressed by Syria's predominantly Shia rulers.
Mohammad Amin, a senior Taliban operative and "co-ordinator of the Syrian base", told the BBC that the cell to monitor "the jihad" in Syria was set up six months ago.

He said that the cell has the approval of militant factions both within and outside of the Tehrik-e-Taliban Pakistan (TTP), an umbrella organisation of militant groups fighting the Pakistani forces.
The cell sends "information and feedback" on the conflict in Syria back to Pakistan, he was quoted as saying.
Their job is to "assess the needs of the Jihad in Syria, and to work out joint operations with our Syrian friends".
"There are dozens of Pakistani hopefuls in line to join the fighting against the Syrian army, but the advice we are getting at the moment is that there's already enough manpower in Syria".
