Last year was the deadliest yet for children in Syria, with more than 1,100 killed by fighting, the United Nations said on Monday, ahead of the bloody conflict entering its ninth year.

U.N. children's agency UNICEF said it had been able to verify 1,106 child deaths from the fighting in 2018 — the highest annual toll since war broke out in 2011 — but that the true figure was likely to be much higher.

"Today there exists an alarming misconception that the conflict in Syria is drawing quickly to a close — it is not," said executive director Henrietta Fore in a statement.
