TEHRAN, July 20 (Xinhua) -- Explosions were heard on Monday evening in Iran's southern provinces of Hormozgan and Fars, the semi-official Mehr news agency reported.
Several explosions were heard in Hormozgan's Sirik County, Mehr cited local citizens as saying, adding the nature of the blast remains unclear.
It also quoted Seyed Ahmad Ahmadizadeh, Fars' deputy governor for political, security and social affairs, as saying that the United States has carried out an airstrike against a region in the provincial capital Shiraz, without causing casualties.
The United States has launched multiple strikes on Iran's southern provinces over the past week, saying they were aimed at "degrading Iran's ability to threaten commercial shipping."
Iran has responded with waves of missile and drone attacks targeting U.S. military bases and facilities in regional countries, including Kuwait, Bahrain and Jordan.
Earlier in the day, Iranian President Masoud Pezeshkian declared a "full-scale war" with the United States, though Foreign Ministry spokesperson Esmaeil Baghaei said Iran has received mediation proposals and keeps its diplomatic channels open. ■
