Saudi Arabia said Syrians should be enabled to protect themselves against government attacks but declined direct comment on a report that it had helped set up a secret liaison center in Turkey to aid a rebellion against President Bashar al-Assad.
Assad on Sunday claimed victory in a hard-fought battle for Syria's capital, Damascus, and pounded rebels who control of parts of its largest city, Aleppo.
Gulf sources told Reuters on Friday that Saudi Arabia, Turkey and Qatar had established a center in Adana, southeastern Turkey, to help the rebel Free Syrian Army with communications and weaponry as it battles in major cities against forces loyal to Assad.
"The very well-known position of the kingdom of Saudi Arabia is to extend to the Syrian people financial and humanitarian assistance, as well as calling upon the international community to enable them to protect themselves at the very least if the international community is not able to do so," a foreign ministry spokesman said by text message on Saturday, answering a Reuters query about the base.

"The Syrian regime is importing and using all kinds of weapons to fight and oppress its own people in a fierce war as if it's launched toward a foreign enemy -- not against its disarmed population", the spokesman added.
The Gulf sources had also said the Adana center, which is near the Syrian border and a U.S. Air Force base at Incirlik, was set up at the suggestion of Saudi Deputy Foreign Minister Prince Abdulaziz bin Abdullah during a trip to Turkey.
However, the foreign ministry spokesman said Prince Abdulaziz, who was promoted to deputy foreign minister last year, and is a son of King Abdullah, had not visited Turkey.
Assad forces declare capital victory
Assad's forces have struggled as never before to maintain their grip on the country over the past two weeks after a major rebel advance into the two largest cities and an explosion that killed four top security officials.
Government forces have succeeded in reimposing their grip the capital after a punishing battle, but rebels are still in control of sections of Aleppo, clashing with reinforced army troops for several days.
"Today I tell you, Syria is stronger... In less than a week they were defeated (in Damascus) and the battle failed," Foreign Minister Walid Moualem said on a visit to Iran, Assad's main ally in a region where other neighbors have forsaken him.
"So they moved on to Aleppo and I assure you, their plots will fail."
Rebel fighters, patrolling opposition districts in flat-bed trucks flying green-white-and-black "independence" flags, said they were holding off Assad's forces in the south-western Aleppo district of Salaheddine, where clashes have gone on for days.
Opposition activists also reported fighting in other rebel-held districts of Aleppo, in what could herald the start of a decisive phase in the battle for Syria's commercial hub, after the army sent tank columns and troop reinforcements last week.
Helicopter gunships hovered over the city shortly after dawn and the thud of artillery boomed across neighborhoods. Syrian state television said soldiers was repelling "terrorists" in Salaheddine and had captured several of their leaders.
