Tasnim � Saudi warplanes carried out fresh strikes against residential areas in Yemen�s northwestern province of Hajjah, killing and injuring 15 people.

Four citizens were killed and 11 others wounded on Monday when the Saudi warplanes pounded civilian areas in Hajjah province, a security official told Saba on condition of anonymity.

The strikes also hit a vehicle in Mostaba district, killing all people on board, the official added.

Yemen�s defenseless people have been under massive attacks by a Saudi-led coalition for more than four years but Riyadh has reached none of its objectives in Yemen so far.

Since March 2015, Saudi Arabia and some of its Arab allies have been carrying out deadly airstrikes against the Houthi Ansarullah movement in an attempt to restore power to fugitive former president Abd Rabbuh Mansour Hadi, a close ally of Riyadh.

According to a recent UN report, the combined death toll from the Saudi-led aggression and disease is 233,000, or 0.8 percent of Yemen's 30 million-strong population.
