This photo released by Azerbaijani Ministry of Emergency Situations on Monday July 5, 2021 shows an aerial view of the aftermath of a strong explosion in the Caspian Sea area, about 10 kilometers (6 miles) from the Umid gas field, which is 75 kilometers (45 miles) off the coast of the capital, Baku. A strong explosion has shaken the Caspian Sea area where Azerbaijan has extensive offshore oil and gas fields and a column of fire rose late Sunday, but the state oil company says none of its platforms were damaged. The cause of the blast is not immediately determined, but state oil company SOCAR says preliminary information indicates it was a mud volcano. (Azerbaijani Ministry of Emergency Situations via AP)
