利比亚当局逮捕了几名与班加西美国大使馆袭击案有关的疑犯。
New Libyan Prime Minister Mustafa Abu Shaqur told the BBC the investigation was making progress.
The attack happened on Tuesday during protests over a US-made film that mocks the Prophet Mohammed.
Similar protests have spread across the Middle East and North Africa. Further unrest is expected at Friday prayers.
Clashes between riot police and protesters continued overnight in the Egyptian capital Cairo, where Islamist groups and others have called for a peaceful "million-man march" later on Friday.
US President Barack Obama has promised to do whatever is necessary to protect US citizens abroad and said he was urging foreign governments to guarantee their security.
A White House statement said he had thanked Yemeni President Abd-Rabbu Mansour Hadi for condemning an attack on the US embassy there and for launching an investigation.
"President Obama expressed appreciation for the co-operation we have received from the Yemeni government and underscored the importance of working together to ensure the security of US personnel," the statement said.
