Arab coalition air strikes hit military targets in the Yemeni capital today, residents said.

Large plumes of smoke could be seen rising from various locations in Sanaa but there were no official reports of casualties.

The strikes came a day after coalition air strikes killed nine people in the Houthi-controlled city of Ibb in central Yemen late on yesterday, medical sources and residents in the area told Reuters.

Nine other people were wounded in the air strikes yesterday in several areas of the city and its outskirts, residents and medics said, adding the nine dead included three children and their parents.

A spokesman for the Saudi-led alliance of Arab countries could not immediately be contacted.

The coalition, which began operations in Yemen in March of last year to try to reverse the rise to power of the Iran-allied Houthi group, has repeatedly said it does not target civilians.

UN-sponsored talks to try to end the fighting that has killed more than 10,000 people collapsed last month and the Houthi movement and allied forces loyal to former president Ali Abdullah Saleh resumed shelling into neighboring Saudi Arabia.
