I'm ABC global affairs editor Laura Tingle coming to you from Dubai. I'm going to give you daily updates to help you quickly understand what's going on.

Here's what you need to know today:

• After "relative" quiet in the Gulf states - with most attacks focused on energy and US assets — the UAE capital of Abu Dhabi came under heavy (but intercepted) missile fire last night. There were explosions also reported in Qatar, Bahrain and more tankers were damaged in the Gulf. Alarms also went off in Dubai.
• A drone strike on an airport in Azerbaijan seemed to be yet another sign of Iran wanting to widen the conflict — though the strange bit here is that Azerbaijan has one of the world’s biggest Shiite populations and is therefore a natural ally of Iran.
• Elsewhere, Israel continues to drive tens of thousands of people from southern Lebanon.

So, what's the fallout?

There is a lot to be said strategically for being unpredictable. And Iran has kept changing its strategy of counterattack in the days since the United States and Israel first started the conflict with the rogue state.

But what if no-one is quite in control?

Middle East analyst Dr Burcu Ozcelik told the ABC on Thursday night that she thought Iran's attack on Azerbaijan was ”a miscalculation”.

“One possibility is that it's caused by confusion and poor decision-making in a very fractured command and control hierarchy in panic mode,” she said. “I think there are also those inside the security apparatus that are seeking escalation to be able to exert more pressure on Washington.”

We always presume people have a cunning plan. But maybe the Iranian military has too many of them just now.

Thanks for joining me. You can keep track of the latest updates from Iran and around the world throughout the day via our live blog.

• Analysis by Michelle Grattan: When Canadian Prime Minister Mark Carney addressed federal parliament on Thursday, his well-crafted speech had one gaping hole: the United States-Israeli strikes on Iran and the subsequent ever-widening conflict that has engulfed the region.
• Super risk: A major market meltdown would change the financial plans of millions of Australians overnight, with the Middle East war yet another danger to the global monetary system, writes ABC business correspondent David Taylor.
• Exposure at the salon: Walk-in nail salons are a mainstay of shopping hubs across Australia, but not enough is known about the health problems and chemical exposure that nail technicians face. Amid calls for research, experts say its time that changed.

• First to go: In breaking news this morning, US President Donald Trump has fired Secretary of Homeland Security Kristi Noem, after mounting criticism over her leadership of the department. Noem had also been under pressure over her handling of ICE raids, describing the two civilians shot dead in Minnesota as engaged in acts of domestic terrorism.
• 'Plucky pensioner': A survivor who was sexually abused by her uncle for a decade says she was in "disbelief" when she heard her abuser was being profiled on the ABC's Australian Story program, which was cancelled just hours before it went to air. 
• Matildas beat Iran: The golden girls of soccer have beaten Iran 4-0 on the Gold Coast, with Amy Sayer's cross-turned-goal starting a goal rush that pushed Australia into the knockout stages of the Women's Asian Cup.

- That's Nicole Kalms, a professor in the department of design at Monash University and a founding director of the Monash XYX Lab, which leads national and international research into gender-sensitive design practices.

She says that phones, medicines, cars, surgical tools, even the temperature in an office were all designed to suit the average man, and that women are an afterthought in the way many products and spaces are designed.

And that man is known as 'Reference Man': a white male, 25 to 35 years old, weighing around 70 kilograms, about 170 centimetres tall and created in the mid-1970s.

"[He] became what I would describe as a kind of default or standard human that was the measure for everything."
