U.S. officials say Washington plans to provide about $100 million in new aid to the Syrian opposition for non-lethal military equipment.

Officials say Secretary of State John Kerry will announce the new aid this weekend at an international conference on Syria that he will attend in Turkey.

The officials say the new assistance will not include any weapons or other lethal equipment. Non-lethal military aid could include items such as body armor, night vision goggles and communications equipment.

Also Friday, the United Nations and Arab League mediator for the conflict in Syria, Lakhdar Brahimi, offered a bleak assessment of the Syrian conflict.
