In what appears to be a new violation of laws and international treaties, Houthi militias refused to allow the UN sanctions team from entering the Yemeni capital of Sanaa and all areas under its control.

During a meeting with Yemeni Prime Minister Ahmed bin Daghr in Aden, UN sanctions team coordinator Ahmed Himmich said in a statement that the delegation seeks to take a stand on the violations that directly affect civilians and brief the UN.

Meanwhile, 14 civilians were killed and injured in a raid carried out by Houthi militias and militias allied to ousted President Ali Abdullah Saleh, which targeted civilian neighborhoods in the center of Taiz City.

Violent clashes took place between government forces and the rebels in the north-east fronts of Taiz, as a result of a violent attack that rebels launched against army and resistant sites east of the city.
