The U.S. Embassy in Ankara, Turkey, closed Monday due to an unspecified security threat.

The embassy will only provide emergency services, and will not renew passports, report births abroad or deliver other nonessential services, the embassy said in a statement. Visa interviews are canceled while the embassy is closed.

The embassy advised those in the area to avoid large crowds, avoid the embassy and “keep a low profile.”

Turkish police detained four suspects Monday as part of an investigation into a possible attack on the embassy, The Associated Press reported, citing Turkish state media. All four are reportedly associated with the Islamic State in Iraq and Syria, and are Iraqi nationals.

The Ankara governor’s office issued a statement late Sunday that extra security measures were taken based on intelligence that “terrorist actions” could take place targeting U.S. citizens, according to local media.
