Washington (CNN) Secretary of State Mike Pompeo spoke Monday with Saudi Crown Prince Mohammed bin Salman, but according to a State Department readout of the conversation, the top US diplomat made no mention of last week's Saudi-led airstrike that hit a school bus in Yemen and killed dozens of children, many under the age of 10.

Pompeo and the White House have failed to publicly address the bombing in recent days, as reports continue to emerge detailing the tragic incident.

According to the State Department, Pompeo "thanked the Crown Prince for Saudi Arabia's support for northeast Syria's urgent stabilization needs, its engagement with the Iraqi government, and its offer to help Iraq address its water and electricity shortages" during Monday's call.

The secretary and the Crown Prince discussed their support for a ceasefire in Afghanistan. The two also "reviewed the UN Special Envoy's work to resolve the conflict in Yemen and other topics of mutual interest," according to the statement.

State Department spokesperson Heather Nauert discussed the bombing only after she was asked by reporters last week. At the time, she said the US is "certainly concerned" by reports of the deadly strike, but that she could not confirm the "all the details because we are not there on the ground."
