The US is to re-open 18 of 20 consulates and embassies and closed this week due to terrorist threat.
The US closed 19 diplomatic missions in the Middle East and Africa last Sunday in response to what it said was a threat of a terrorist attack.
The US embassy in Yemen and the consulate in Lahore, Pakistan will remain closed due to continuing concerns about a possible al Qaeda attack.
"We will continue to evaluate the threats to Sanaa and Lahore and make subsequent decisions about the reopening of those facilities based on that information," said spokeswoman Jen Psaki.
"We will also continue to evaluate information about these and all of our posts and to take appropriate steps to best protect the safety of our personnel, American citizens travelling overseas, and visitors to our facilities."
