David Hale, U.S. undersecretary of state for political affairs, called for a thorough and transparent investigation.
Hassan Nasrallah said the cause of the explosion is still unclear, adding that any international probe would also have to clear Israel of any responsibility in the port explosion.
On Friday, the United Nations launched a $565 million appeal for Lebanon with immediate humanitarian assistance and initial recovery efforts.
