Eerie Black Ring UFO Captured on Video in Mexico

• When: July 13th, 2017 (date still being confirmed)
  
• Where: Progreso de Madero,  Mexico (near Mexico City)
• What: Ring of strange smoke or fog hovering

In a small town outside Mexico City, a local appears to have filmed a strange round smoky UFO hovering overhead:

"Stunned eyewitnesses filmed the phenomenon with their smartphones in the small town of Progreso de Madero in the Quecholac municipality of central Mexico's Puebla state.

The footage, which shows a huge black ring hovering in the sky, left local residents baffled.

Some were convinced that it was a flying saucer while others, pointing out that it was partially enveloped in cloud, thought it was a weather-related phenomenon.
Eyewitnesses can be heard in the background of the video trying to explain the apparition.

One woman asks: "What is that?", and a man replies: "A flying saucer?"

Another woman speculates: "It's a rain formation", but the man counters: "No, it's not, it's a black wheel", and the woman notes: "It's going up."

The black ring quickly disappeared from view and there is still no official explanation for it.

Netizen 'Alejandro Lopez Robles' was convinced he had seen something otherworldly, commenting: "It's a flying saucer."

Many major news outlets, including AOL, reported on the footage, however I am having trouble finding additional local accounts of the event.

Smoke rings are a common UFO phenomenon, however,  so this video is not terribly  difficult to believe. Could the sighting be more weather, versus alien, related, however? Compare this video to other similar sightings over the past few years:

Beyond strange weather, pollution or even exhaust from an explosion could be to blame, as demonstrated in the picture below:
