BEIRUT, Lebanon- UN chief, Antonio Guterres, denounced "the recent and sharp escalation in the Yemen conflict," after strikes targeting rebels were met with an attempted attack, aimed at Saudi Arabia.
The Saudi-led coalition said, it was behind two air raids on the office of the presidency in Yemen's rebel-held capital, which were reported to have killed six people and wounded dozens.
On Wednesday, Saudi Arabia's air defences intercepted two ballistic missiles, over the capital Riyadh, the latest in a series of attacks claimed by rebels in neighbouring Yemen.
Guterres is "deeply concerned" over the exchanges, his spokesman, Stephane Dujarric, said in a statement.
"The Secretary-General appeals to the parties to refrain from further escalation, as this adversely impacts the chances for peace," the statement said.
"The Secretary-General reminds all parties to the conflict that they must uphold international humanitarian law, including taking steps to protect civilians."
Since Nov, the Iran-backed Houthi rebels have intensified missile attacks into neighbouring Saudi Arabia, including targeting its capital.
