As the US-Iran war escalates, more countries in the Middle East have—officially or unofficially—entered the fray over the past week. Saudi Arabia said July 30 that 14 countries (including Egypt, Türkiye and Bahrain) have so far joined an alliance it set up to protect shipping and energy supplies through the Bab al-Mandeb Strait, Red Sea and Gulf of Aden. The alliance, which the kingdom calls defensive, formed in reaction to the blockade by Yemen's Houthi rebels against Saudi ships in the strait. Among those that has signed on is the internationally recognized (but largely exiled) government of Yemen, which would presumably be onside with reported plans by Saudi Arabia to launch a ground offensive against the Houthis.

Bahrain's High Criminal Court held its first hearing July 5 in a national security case involving 19 defendants accused of forming and operating a terrorist organization linked to Iran’s Islamic Revolutionary Guard Corps (IRGC).

The United States and Iran have signed a Memorandum of Understanding that aims to end the war the US and Israel launched on Iran on Feb. 28. The 14-point agreement, signed by Donald Trump at a June 17 gathering hosted by French President Emmanuel Macron in the Palace of Versailles—where the treaty to end World War I was signed in 1919—opens up the Strait of Hormuz for a 60-day ceasefire window, during which the two sides have vowed to negotiate a long-term resolution to the Iranian nuclear standoff. The US will also terminate all sanctions against Iran, provide $300 billion for post-war reconstruction, and unlock all frozen Iranian funds and assets.

After five weeks of war, the US and Iran on April 8 agreed to a two-week ceasefire brokered by Pakistan. Its basic details, however, and to what extent it will be implemented, are surrounded by uncertainty. A main sticking point is the question of whether Lebanon was included in the deal. Iranian and Pakistani officials are insisting it was, but the US and Israel say that it wasn't. Meanwhile, Israel has continued to carry out devastating attacks on Beirut and other parts of Lebanon.

UN Human Rights Chief Volker Türk warned April 1 that repression of freedom of expression across the Middle East has deepened significantly since the US-Israeli attacks on Iran commenced at the end of February.

United Nations officials said on March 10 that US and Israeli airstrikes on fuel depots in Tehran have released large amounts of toxic pollutants, producing acidic "black rain" across parts of the capital.

The United Nations on March 3 urgently called for civilian protection amid growing violence and instability in the Middle East—and particularly in regard to the ongoing US and Israeli military operations against Iran. The UN urged a thorough investigation into a deadly strike on a girls' school in Iran, and requested the disclosure of all relevant information.

On Feb. 28, the United States and Israel launched coordinated military strikes on Iran, hitting targets in Tehran, Isfahan, Qom and other cities across 24 provinces. Iran's Red Crescent reported at least 201 people killed and 700 injured. US President Donald Trump announced "major combat operations" and openly urged regime change. Iran retaliated by launching missiles at Israel and US military installations across the Gulf States.
