The U.S. Embassy in Zimbabwe is instructing Americans to find “shelter in place until further notice,” due to ongoing “political uncertainty” throughout the night.

Armed soldier and military vehicles were seen in the streets of Zimbabwe’s capital, Harare, and at least three explosions were heard on Wednesday morning, local time, according to the Associated Press.

The embassy also said it will be closed to the public on Wednesday and employees have been told to remain home.

“Even demonstrations intended to be peaceful can turn into confrontational and escalate into violence,” the embassy said in a statement. “Avoid areas where demonstrations are taking place and exercise caution when in the vicinity of any large gatherings, protests, or demonstrations.”

The British Embassy also instructed citizens early Wednesday morning, local time, to remain inside “until the situation becomes clearer.”

Members of Zimbabwe’s military and the president, Robert Mugabe, who has been president since 1980, are reportedly at odds and there are rumors of a coup attempt, including a takeover of a national broadcaster.

A military spokesman claimed that they are taking action to "target criminals," and added that this was not "a military takeover of government," according to BBC.
