A prominent UAE human rights activist, Ahmed Mansour, has been on hunger strike for more than three weeks to protest his prison conditions, Amnesty International said.

In 2018, Mansour was sentenced to 10 years' imprisonment for several charges, notably posting false information on social media platforms, insulting the UAE's status and symbols, and damaging the country's reputation abroad.

Mansoor is a prominent human rights activist in the UAE, also a blogger, and won the Martin Ennals Award for Human Rights Defenders in 2015.

The UAE authorities arrested Mansour in March 2017 and tried him in May 2018 amid domestic and international convictions.

Commenting on reports of Mansour's hunger strike in May, the UAE said he was not on a hunger strike, regularly undergoing medical tests and in good health, she said.
