Hundreds of Saudis, perhaps even several thousand, have gone to fight against the government in Syria, and judging by death notices and other postings on social networks, their numbers show no sign of abating.
Earlier this month, an extremist website announced the death of Rashid al-Shelwi, an engineer from the Saudi city of Taif, while fighting alongside the western-backed militants in Syria.
On Thursday, the Syrian Observatory for Human Rights reported that a militant who appeared in a recent video posting, executing captured government soldiers, was a Saudi using the nom de guerre Qaswara al-Jazrawi.
Like a significant number of Saudi militants, Jazrawi fights in the ranks of the Al-Nusra Front which has pledged its loyalty to Al-Qaeda.
Now after months of financial and military support to the militant groups, Saudi authorities are concerned about spread of the war to the kingdom as it did during the war in Iraq after US invasion to the country in 2003.
Last June, Saudi Arabia's Council of Senior Ulema, which is headed by Shaikh, already issued a fatwa, or religious edict, prohibiting jihad in Syria without permission from the authorities.
Stephane Lacroix, a specialist in Saudi extremism says "From the mid-80s, the Saudi authorities gave official support to young Saudis who wanted to go to fight the Soviets," he said.
"A number of these 'Arab Afghans' were later involved in acts of violence in Saudi Arabia."
However Saudi officials which are widely blamed by the Syrian government of fueling the war in the country try to play down the number of Saudis fighting in Syria.
Interior ministry spokesman General Mansur al-Turki said last month that he did not believe there were many.
However along with reports of a large number of Saudi militants killed in Syria, there are reports showing that not only Saudis go to fight in Syria but also they provide a considerable amount of financial and military support to anti-government insurgents.
According to an article published by the Financial Times, after Qatar, Saudi Arabia is the largest provider of weapons to the terrorists and militant groups in Syria.
Syria has been struggling with a western-backed insurgency which began in March 2011 as a protesting movement soon turned to be a cover for terrorist groups including al-Qaeda and al-Nusra Front.
The United States, Israel, UK and their allies as well as several Arab countries, inclusion Qatar and Saudi Arabia have been supporting the armed insurgency in Syria, mulling ways to supply the militants with more arms to topple the legitimate government of Syrian President Bashar al-Assad.
