During the last 10 years, around 10 million children are estimated to have been killed as a result of war, reports the
Children's Rights Portal . The site categorizes child war victims as civilian victims, soldiers, displaced, orphans, wounded or handicapped, imprisoned and exploited children (sexual exploitation or even forced labor). Despite the fact that the right of children of survival and protection are guaranteed according to the Vienna Declaration and Programme of Action  (VDPA), and UN Convention on the Rights of the Child , which was signed on 20 November 1989, children continue to suffer around the world.
UN Convention on the Rights of the Child, Article 19: State Parties must “take all appropriate legislative, administrative, social and educational measures to protect the child from all forms of physical or mental violence”
Since March 2011, when the Syrian revolution erupted against Bashar Al Assad's regime, the children of Syria were among the first victims of violence, torture, and killings. According to HRW report: “We’ve Never Seen Such Horror”  on June 2011:
The protests first broke out in Daraa in response to the detention and torture of 15 children accused of painting graffiti slogans calling for the government's downfall . In response and since then, security forces have repeatedly and systematically opened fire on overwhelmingly peaceful demonstrators. The security forces have killed at least 418 people in the Daraa governorate alone, and more than 887 across Syria, according to local activists who have been maintaining a list of those killed. Exact numbers are impossible to verify.
Ever since, an estimated 4,355 Syrian children been killed (up to 15/1/2013) according to the latest report released by Martyrs of the Syrian Revolution Database . Besides thousands more are wounded, detained, or left without a family, or medical aid and humanitarian assistance. Human Rights Watch, for instance, shares evidence,  which shows that cluster bombs was used to killed children at the hands of the regime's air forces.
On January 18, UNICEF's Regional Director for the Middle East and North Africa Maria Calivis stated :
“A series of reports from Syria this week underlines the terrible price children are paying as long as conflict in the country rages.
Meanwhile, Syrian children are the forgotten victims of the 22-month conflict. The number of children's lives lost continues to accumulate every day; and Syrian activists have no choice but to post the bad news on social media.
Here's a round up of reactions from Syrian netizens on Twitter:

Dozens of Children Murdered in Syria
On May 25, 2011, after almost a month in custody, the world heard the horrifying story of torturing and killing of Hamza Ali AlKhateeb , a 13-year-old Syrian boy who died allegedly while in the custody of the Syrian government in Daraa.
His death showed numerous injuries, including broken bones, gunshot wounds, burn marks, and mutilated genitals
One year after Hamza's martyrdom story, Al-Houla Massacre  took place. On May 25, 2012, activists blamed forces loyal to Bashar al-Assad of murdering 108 Syrians, including 25 men, 34 women and 49 children under the age of 10 (per U.N. observers) by in the town of Al-Houla in Homs. The next footage [Warning: Graphic, Children Death] depicts the aftermath of a massacre showing children bodies, and human parts covered with blood.
Syrian children are paying the price of war between adults in Syria. Syrian refugee children are overwhelmed, as they have never imagined being caught in such a situation. The Syrian Organization for the Defense of Human Rights  wrote on its Facebook page on December 28, 2012:
Almost 4,000 Syrian children have been killed so far in Assad's war on Syria, tens of thousands more are maimed and wounded, all are traumatized and terrorized.. Question for World leaders How many murdered children will it take to make a ‘red line'? by a regime that sees them as legitimate targets.
Many initiative are available to help the children of Syria. For instance, people can donate  to Save the Children  to provide warm clothes, shoes, and blankets for children. Winter aid packages specially-made for infants are available.
Hopefully, we could make a difference as Leila hoped on Twitter:
