Saada is the heartland of the Iran-backed Shia Huthi rebels the coalition has been fighting since March last year in support of the Yemen government.
Janne-Anne McKenna, Director of MSF Ireland - wants the incident investigated:
Last October an MSF hospital in Afghanistan was hit by a US air strike, killing at least 22 people.
Barack Obama later called the head of the aid agency to apologise.
Later in October, one of the organisation's hospitals in north Yemen was destroyed after being hit by two air strikes.
However, all staff and patients were successfully evacuated after the first strike hit an area of the hospital that was not in use. Two people sustained minor injuries.
The international coalition carrying out airstrikes was also accused of bombing MSF's clinic in Taez, southwest Yemen, last month leaving nine people injured.
