The UN and its partners estimate that as many as 600,000 civilians are now living in and around Hodeida.
"During the long study and calculation, we found that as many as 250 000 people lost everything they had - even my life".
Col Al Malki said the coalition was working with worldwide NGO partners to create conditions for them to work safely and freely in Yemen and was fully prepared to assist the ICRC to ensure the continuation of its operations in the country.
Some 450 ICRC employees remain in Yemen, including dozens of expatriate staff, spokeswoman Marie-Claire Feghali said.
"The security of our staff, who are being intimidated by parties to the conflict, is a non-negotiable prerequisite for our presence and work in Yemen and an absolute priority", the statement said.
Stillhart said: "While the Yemen delegation has received numerous threats in the past, we can not now accept additional risk less than two months after a gunman killed a staff member. There is an overall degradation of the security in all the areas we operate in Sanaa, Saada, Taiz, Aden and Hodeida" provinces, she said.
"While the Yemen delegation has received numerous threats in the past, we can not now accept additional risk less than two months after a gunman killed a staff member", the organisation said, referring to the killing of a Lebanese employee in Yemen's southern city of Taez in April.
The first missile fell down inside the Yemeni territories while the other fell down in an unpopulated desert, Saudi Press Agency (SPA) said, adding no casualties have been reported.
Since then, more than 10,000 people have been killed, a lot of them civilians.
