The U.N. says at least 2,355 civilians have been killed in fighting since March, when the coalition began launching airstrikes against Shiite Houthi rebels and allied army units, who control the capital and are at war with the internationally recognized government as well as southern separatists, local militias and Sunni extremists.

U.N. spokesman Stephane Dujarric said Ban strongly condemns Friday's "murder" of 18-month-old Ali Dawabsheh and calls for the perpetrators to be brought to justice.

"The absence of a political process and Israel's illegal settlement policy, as well as the harsh and unnecessary practice of demolishing Palestinian houses, have given rise to violent extremism on both sides," Ban's spokesman said.
