BEIRUT (AP) — An international rights group said Friday that Syria’s government was obstructing aid to war-torn areas by denying aid agencies permission to use rebel-held border crossings, affecting the lives of some 3 million Syrians living in tough-to-reach places.

Human Rights Watch said Syria only allowed aid organizations to use the one border crossing with Turkey that remains in government hands near the far northern city of Qamishli. The crossing was opened to aid supplies earlier this month.
