The spokesperson of the Rupert Colville office told press in Geneva that the air strikes left 117 dead and 129 injured in the Arabic Peninsula country, where the number of dead increased to 168 and the injured to 193 in February.
Yemen is facing a conflict between rebels and the Government, which escalated in March 2015 with the beginning of the Saudi and its Sunni allies' anti-insurgent bombings.
According to Colville, Sanaa capital has been the most affected by the Saudi-led air attacks.
A decrease in losses left by those attacks was seen in this country last November, but since then there is a significant increase, regretted Colville.
According to the UN High Commissioner Office for Human Rights, 3081 people have been reported dead and 5733 injured in Yemen since last March 26, figures that exclude fighters.
One of the worst incidents registered by the coalition air strikes took place last February 27, in which 39 civilians, including nine children, lost their lives and 33 were injured in a crowded market in Sanaa.
It is the highest death toll in only one air attack, following the 41 people massacred in another market in Sanaa five months ago, noted Colville.
