More than 25 children are among the 1,000-plus deaths in Syria since anti-government demonstrations began in the country, an opposition group revealed Wednesday.
The Local Coordination Committees in Syria -- which has organized protests against Syrian President Bashar Assad -- said some of the children died "under severe torture."
So far, the National Organization for Human Rights has documented 1,062 killings since uprising began in Syria 9 weeks ago.
Protesters have tried since mid-March to get Assad to step down from power. Instead, any opposition challenging his family's 40-year-old dynasty has been met with force.
The harsh reaction has triggered international outrage as well as U.S. and European sanctions, including an EU assets freeze as well as a visa ban on Assad and nine members of his regime.
The lack of organized resistance from the opposition has been one of the weaknesses of the uprising.
The opposition is planning a conference in Turkey to find a common voice for its anti-government movement. The event will include opposition figures, writers, journalists and activists.
"The idea is to show that the opposition can put aside ideological differences and unify under the banner of freedom," said Amar Qurabi, head of the NOHR in Syria.
Meanwhile, Syrian activists have called for a fresh wave of protests in eastern and northern parts of the country, Wednesday.
The demonstrations are in solidarity with the southern town of Daraa, which has been under siege by the Syrian military for the past five weeks.
