UNITED NATIONS (AP) — A key U.N. committee voted overwhelmingly Tuesday for a resolution strongly condemning “gross violations of human rights and fundamental freedoms” by Syrian authorities and government-controlled militias and demanding an immediate halt to the violations and attacks against civilians.

The resolution urges Syrian authorities to immediately release all detainees and calls for a prompt independent international investigation into abuses and violations of international law with a view to bringing to justice those responsible for war crimes, crimes against humanity and other crimes.
