Nearly 900 children were killed in violence in Iraq between 2008 and 2010 and more than 3,200 wounded, UNICEF said in a report on Wednesday marking the "Day of the Iraqi Child."
Quoting government figures for child casualties, it said 376 children were killed and 1,594 wounded in 2008, while 362 died and 1,044 were hurt the previous year.
During the first nine months of 2010, 134 children died in violence and 590 were wounded, the report said.
Children accounted for 8.1 percent of all casualties in attacks during the period, UNICEF said, adding it "remains concerned about the indiscriminate violence that continues to violate the rights of children in Iraq."
The Day of the Iraqi Child was named after 32 children were killed by a car bomb on July 13, 2005, as they rushed toward American soldiers offering them candy and toys.
The UNICEF report also noted that attacks against schools and professionals in the education sector, such as teachers and administrative staff, "have significantly increased," impacting children's right to education.
During May and June, 11 incidents were documented to have targeted or affected schools, teachers and education officials, the report said.
