Yemen's human rights situation continued to deteriorate in 2010. Amid political unrest in the south, hundreds of arbitrary arrests and the use of lethal force against peaceful demonstrators undermined advances in the rule of law. Skirmishes tested a truce in the conflict with Huthi rebels in the north, and government ministries, the army, rebels, and "tribes" in various conflict affected northern areas obstructed humanitarian assistance. Accountability for laws of war violations remained lacking. Yemen intensified counterterrorism efforts against suspected al Qaeda members in the Arabian Peninsula (AQAP), but some attacks killed and injured civilians.
