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.

Suspected Jewish assailants set fire to a West Bank home on Friday and burned a sleeping Palestinian toddler to death in an attack that drew Palestinian rage and widespread Israeli condemnation.
