JERUSALEM (CNN) - A Catholic monk was not among the men beheaded in a gruesome video circulating online, a friar who oversees monks in the Middle East told CNN in an exclusive interview.
Father Francois Mourad, a Syrian, was killed June 23 at a Catholic monastery in Gassanieh, said Friar Pierbattista Pizzaballa, head of the Franciscan Custody of the Holy Land.
Mourad was buried the same day in a nearby village, the friar said.
A nine-minute video, which appears to have been shot with a handheld device, shows three men being beheaded on a grassy hill while a crowd shouts, "Allahu Akbar!" -- Arabic for God is great. It is not clear where or when the video was shot.
A number of Catholic websites in the United States have posted the video online, saying that Mourad was among the three beheaded men.
"I deny this vigorously," Pizzaballa said. "He has nothing to do with this video and with (these) three poor persons."
Pizzaballa said he had seen the video, which he called "shameful."
In a statement Friday, the Custody of the Holy Land also denied media reports that three friars had been killed in Syria recently.
Headquartered in Jerusalem, the Custody includes about 285 Franciscan friars and covers Israel, the Palestinian territories, Egypt, Jordan and Syria.
Pizzaballa said that Mourad sought refuge at Gassanieh because it was considered to be safe from Syria's bloody civil war, which has claimed more than 93,000 lives, according to the United Nations.
The Vatican has not commented on the video and referred questions to Pizzaballa.
A June 25 report from Vatican Radio -- the church's official broadcast -- said that Mourad was killed during a raid on the Franciscan monastery of St. Anthony of Padua in Gassanieh, a predominantly Christian village near the Turkish border.
Mourad was well-known in the region, according to the Franciscans. He had retired there to live a contemplative life as a hermit. As the war wore on, he sought refuge at the monastery.
Several Franciscans, four nuns and 10 Christians also lived at the monastery, which was considered safe until the raid, according to Pizzaballa.
"When (Father) Francois tried to oppose resistance to defend the nuns and other people, the guerrillas shot him, killing him," according the Vatican Radio report.
Most of the village's Christian population has fled, Pizzaballa told Vatican Radio, after weeks of assaults by Islamist rebels.
"Mourad was just one of the many men and women religious putting their faith on the front line in Syria, refusing to abandon the communities they serve, Christian and Muslim," Vatican Radio said.
"They stay because they want to be a sign of hope, light and comfort to people in the midst of destruction."
