In a rare step, Abdul Khaliq Abdullah, a UAE political science professor and former crown prince adviser to Abu Dhabi, hoped the Saudi government would soon release Hattun al-Fassi, who had been detained for months.
"Good friends and serious academic colleagues, I hope to meet him soon," wrote Abdul Khaliq on his Twitter account, under the picture of the Academy and champion of women's rights.
In a rare case where a community leader in the UAE talked about the arrest of a female activist in Saudi Arabia, Abdul Khaliq has been severely criticized by some Twitter users for publishing the tweet.
In June, Saudi authorities arrested a number of prominent women's rights defenders in the country, including Fassi, without official charges.
The kingdom has been the target of a wave of criticism from international human rights organizations. The statement of holding activists in Saudi Arabia has also triggered a diplomatic crisis between Canada and the United States earlier this year.
