(CNN) The US Embassy in the Democratic Republic of Congo's capital said Saturday it has received "credible and specific information of a possible terrorist threat" against US facilities in Kinshasa.

"US citizens in Kinshasa and throughout the DRC are strongly encouraged to maintain a heightened level of vigilance and practice good situational awareness," said the embassy. "Keep a low profile and notify friends and family of your safety."

The embassy will be closed to the public Monday because of the threat.

The embassy also warned of potential unrest in the weeks leading up to the December 23 election, saying it "could occur on short notice."
