Images of children killed in a government crackdown against protests are circulating widely among Syrians on YouTube and Al-Jazeera, Facebook and opposition websites.
And they are stoking even more fury against a regime the opposition says has lost all legitimacy.
The images grow no less shocking with time — a gaping wound on a tiny skull, the hair matted with blood; a gunshot that pierced the skin of a small torso and went straight toward the kidney; and finally, the broken neck and severed penis of a 13-year-old boy, his mangled body contorted on a plastic sheet.
Syria's government tried to blunt the anger with promises Wednesday to investigate the killing of 13-year-old Hamza al-Khatib, whose tortured and mutilated body turned him into a symbol of the Syrian uprising.
Amnesty doesn't sway protesters
But protesters deride that and other government concessions, including an amnesty that freed political prisoners on Wednesday and a committee to prepare for national dialogue, as nothing more than a ploy to buy time for President Basher Assad.
They say at least 25 children are among more than 1,000 dead, with government crackdowns that increase the toll almost daily.
The deaths of two girls — a 12-year-old killed Saturday when her school bus came under fire, and an 11-year-old shot to death Tuesday while her town was being shelled — appeared certain to inflame tensions. Already, a Syrian opposition page refers to the older girl, Hajar Tayseer al-Khatib, as "the flower of Syria's martyrs."
Military operations in southern and central Syria killed 33 people Tuesday and Wednesday, even as the government released hundreds of political prisoners. The government claims the revolt is the work of Islamic extremists and armed gangs.
Rami Abdul-Rahman, director of the Syrian Observatory for Human Rights, told The Associated Press that more than 500 prisoners were freed, including some who took part in the latest demonstrations marking the most serious challenge to the Assad family's 40-year rule.
An estimated 10,000 arrested
Activists say 10,000 have been rounded up since the protests began in mid-March.
Syrian state television on Tuesday said the amnesty covered "all members of political movements," including the outlawed Muslim Brotherhood, which led an armed uprising against Assad's father in 1982. Membership in the party is punishable by death.
In Paris, French Foreign Minister Alain Juppe said the amnesty was too late.
Juppe, speaking on the France Culture radio station, said Syrian authorities must be "much clearer, much more ambitious, much bolder than a simple amnesty."
The anger over the children's death appeared unlikely to abate.
Leading Facebook page The Syrian Revolution 2011 addressed the regime directly in a posting: "Why do you hate our children. They are the symbol of our revolution. They are our freedom and the future of our country."
Many of the dead children were from the southern province of Daraa, where the uprising was touched off by the arrest of 15 teenagers who scrawled anti-regime graffiti on the walls of the provincial capital.
At the time, those teens became the symbol of the new revolt inspired by the toppling of regimes in Egypt and Tunisia.
Boy becomes symbol
Hamza, the 13-year-old boy who was arrested during a protest, tortured and killed, has become a new emblem of the uprising. Thousands of people now carry his smiling photo during protests or post it as their Facebook profile. A Facebook page set in his memory has more than 66,000 fans.
Opposition supporters posted a video on YouTube showing Hamza's injuries. His body, lying on a plastic sheet, appeared pink and the eyes were mottled with bruises and black marks.
The video sparked outrage in Syria and around the world.
"I can only hope this child did not die in vain but that the Syrian government will end the brutality and begin the transition to real democracy," said U.S. Secretary of State Hillary Clinton.
Opposition groups in Syria blamed security forces for the boy's death.
State-TV aired an interview late Tuesday with Dr. Akram Shaar, who examined al-Khatib's body. He said the cause of the death was shooting, and three bullets had hit the boy's body.
He added that what appeared to be bruises and signs of torture were the result of natural decomposition since the boy died on April 29. His body was handed over to his family on May 21, state TV said.
Father meets Assad
The station also aired a recorded interview with Hamza's father who said he was received by Assad this week. The father added that the president considers "Hamza as his son and was touched" by the death.
On Tuesday, UNICEF called on all parties to spare civilians, particularly children and women, and urged the government to investigate allegations of the detention and torture of children.
Human Rights Watch said in a report released Wednesday that hundreds of people were detained daily in the province of Daraa and "the detainees, many of them children, were held in appalling conditions."
On April 22, two boys whose ages were 7 and 10 were shot dead by security forces in the southern village of Izraa. A video aired then showed a man ran carrying the body of a young boy, whose hair was matted with blood from a gaping head wound.
Zuhair Awad al-Amar, 8, died after he was shot near the kidney on May 21 in the southern village of Nimr. A YouTube video showed his injury as a narrator said "these are the reforms of Bashar Assad."
