The U.S. Embassy in Zimbabwe says it will be closed to the public on Wednesday because of “ongoing uncertainty” in the capital.

The embassy announced the closure on Twitter early Wednesday, shortly after at least three explosions were heard in Harare and military vehicles were seen in the streets. The embassy says it will remain “minimally staffed.”

Tensions are high after Zimbabwe’s army commander threatened to have the military step in and calm political turmoil and the ruling party accused him of “treasonable conduct.”

Zimbabwe for the first time is seeing an open rift between the military and 93-year-old President Robert Mugabe.
