The Arab coalition on Tuesday called for an immediate ceasefire in Yemen's interim capital of Aden, saying it will take all necessary measures to restore security.
"The coalition renews its call to all parties to ceasefire immediately and end all forms of armed conflict," it in a statement cited by the Saudi SPA agency.
"The coalition affirms that it will take all necessary measures to restore security and stability in Aden," the statement said.
It regretted that all sides did not respond to its earlier calls for restraint and calm.
It also called on the Yemeni people to focus on the principal goals of restoring legitimacy in the country and safeguarding the state.
Coalition spokesman Col. Turki Al-Maliki said on Monday that more than 19 ships are at Yemeni ports carrying humanitarian aid for the Yemeni people.
Maliki said that the coalition called on all political and social communities in Aden for calm and to cooperate with the legitimate government.
The battle should be focused against the Houthi militias, he stressed.
He also denied differences with the United Arab Emirates.
