New York (CNN) -- A top United Nations official on Monday told the Security Council she has "run out of words" to describe the worsening situation in Syria.
"Every time we use a new figure in relation to the Syrian crisis, we say that it is unprecedented. We have run out of words to fully explain the brutality violence and callous disregard for human life which is a hallmark of this crisis," Valerie Amos, the U.N. chief for humanitarian affairs said.
