The US launched a wave of strikes against Iran on July 15, after it reimposed a naval blockade in a return to war between the two foes. Nearly a month after they signed a memorandum of understanding towards ending the Middle East war, the two sides resumed fighting with strikes on targets across the region.

Hostilities in the Middle East intensified on Saturday after a seventh straight night of US attacks on Iran, with Tehran threatening a "full-scale offensive" in response and the strategic Strait of Hormuz remaining virtually closed.

Here are the latest developments:

Bahrain's army said its "air defence systems thwarted" a wave of Iranian attacks on Saturday, as an AFP journalist in Manama reported hearing blasts after sirens sounded.

Kuwait said Iran struck another of its power and water plants, leading to the deactivation of several power generation units, a day after a similar attack.
