Saudi Arabia has insisted that rebels fighting against Syrian President, Bashar al-Assad, must be armed.
The comments from Syrian Foreign Minister came after warning that the involvement of Iran and Hezbollah in Syrian conflict is dangerous.
Saud al-Faisal made the comments after talks in Jeddah with US Secretary of State John Kerry, who is seeking to organise support for the anti-Assad forces amid fears in the West that extremist opposition groups are becoming too powerful, the Guardian reports.
Kerry also met Saudi intelligence chief, Prince Bandar bin Sultan, who co-ordinates the kingdom's overall effort to topple Assad.
Saudi Arabia is already sending arms to rebel groups, and recently sent anti-aircraft and anti-tank weapons.
The new emir, Sheikh Tamim, who took over from his father in a rare peaceful transition on Tuesday, is not expected to change policy on Syria, according to sources in Qatar.
According to the report, Prince Saud said Saudi Arabia 'cannot be silent' at the intervention of Iran and Hezbollah, both close allies of Assad.
