Members of Iraqi online jihadist forums have called for fighters and arms to be sent to aid Syrians opposing President Bashar al-Assad's regime, who have faced a brutal crackdown since March.
Sunni jihadist sites such as Honein and Ansar al-Mujahedeen display numerous comments and articles critical of Assad's regime, and videos of bloody events they say took place in Syria.
The Syrian regime is largely made up of minority Alawites, an offshoot of Shia Islam, while protesters demanding reforms are largely from its Sunni majority.
UN High Commissioner for Human Rights Navi Pillay has said that at least 4,000 people have been killed in the crackdown in Syria over the past eight months, and tens of thousands arrested.
Syrian army deserters have also formed the Free Syrian Army which is inflicting growing losses on regular forces.
Al-Mansur, a poster on the Honein forum, wrote an article entitled, "What is Required of Us Towards our Brothers, the Revolutionaries in Syria," in which he called for "providing all kinds of support to your brothers, from what you have, my Iraqi mujahedeen brothers, in skills and experience."
"Our jihad [holy war], my brothers in Iraq or Syria is for one purpose, which is raising the banner of monotheism, the banner of Allahu akbar [God is greatest]."
"The duty of jihad," Al-Mansur wrote, "is coming to you again."
Another poster, Obeid Allah, said in article entitled "The role of Iraqi Jihadist Organizations in What is Happening in Syria" that "some may say they are busy in Iraq, but I say to them that the Iraqi organisations have significant capabilities in Syria, in all aspects."
He called on "our brothers ... who left Iraq to Syria" to form "security patrols to help our brothers from the Syrian people, as you have experience and skills ... and they information and logistical support."
On the Ansar al-Mujahedeen forum, Sheikh al-Mujahid Abi al-Zahra al-Zubaidi advised the Syrian opposition to "buy weapons and arm yourselves with them and seize them from stockpiles, for this is your only chance to remove the tyrant of Syria and his soldiers."
He also advised Assad opponents to coordinate with the Islamic State of Iraq, Al-Qaeda's front organization here, and to "listen to them and follow their orders and be good soldiers for them."
The stances of those posting on the forums is at odds with that of Iraq's Shia-led government, which has so far shied away from punitive measures against Assad's regime, abstaining from both a vote to suspend Syria from the Arab League, and another to impose sanctions against Syria.
Analysts have said that the Iraqi government's response to the situation in Syria has confessional overtones and may boost Sunni-Shia sectarian divisions there.
