Qatar 'regrets' infringing on female passengers' personal freedom

Qatar said Wednesday it "regrets" infringing personal freedoms, as it explained invasive examinations of female passengers during a search for an abandoned baby's mother at Doha airport.

Earlier this month, women were removed from a Sydney-bound Qatar Airways flight in Doha and forced to undergo vaginal inspections after a newborn was found abandoned in a Hamad International airport bathroom.

"While the aim of the urgently-decided search was to prevent the perpetrators of the horrible crime from escaping, the State of Qatar regrets any distress or infringement on the personal freedoms of any traveller caused by this action," a statement posted on a government website said.

The emir, Sheikh Tamim bin Hamad Al-Thani, said in the statement that a "comprehensive, transparent" investigation would be carried out.

He added that Qatar was "committed to ensuring the safety, security and comfort of all travellers transiting through the country".

The incident has sparked a diplomatic row between Australia and Doha, with Canberra lodging protests with the Middle East nation over the treatment of its citizens.

On Wednesday, it also emerged that the number of planes targeted was much greater than first thought.

Australia's Foreign Minister Marise Payne told parliament women on "10 aircraft in total" had been subject to the searches she has described as "grossly disturbing" and "offensive".

Payne said 18 women -- including 13 Australians -- on an October 2 flight to Sydney were affected, along with "other foreign nationals". AFP understands one French woman on the flight was among them.

The incident may have upended Qatar's efforts to boost its reputation before the Gulf state hosts the football world cup in 2022.

Doha has invested heavily in its airline, the broadcaster Al-Jazeera and social projects that include women's health and educational initiatives.

But the conservative Muslim monarchy, where sex and childbirth out of wedlock are still punishable by jail terms, has struggled to reassure critics that its promises on women's rights, labour relations and democracy are credible.
