"It is no longer surprising to see the Arab League, which is supposed to be concerned with joint Arab action, turn into an instrument of injustice aimed at destabilising Syria," said the daily Ath-Thawra.

The United Nations on Friday said more than 3,000 people, including 187 children, have been killed in a fierce crackdown on the dissent.
