NNA - The United Nations expressed concern on Tuesday over Turkey's use of mass arrests amid nationwide protests against the detention of Istanbul's opposition mayor, urging authorities to investigate allegations of unlawful use of force against demonstrators, according to Agence France-Presse.

"We are deeply concerned that Turkish authorities have arrested at least 92 people over the past week, including Ekrem İmamoğlu, the democratically elected mayor of Istanbul," said Liz Throssell, a spokeswoman for the UN Human Rights Office, in a statement.

She noted that more than 1,000 people, including journalists, have been detained during the protests.
