“Iranian authorities must release all those arbitrarily detained and should relocate other prisoners away from locations at risk of being attacked by Israel," Amnesty International said Monday.

"Prison security forces must not use force or firearms against distressed prisoners,” the rights group said in its statement.

Amnesty also said it is extremely distressed by video footage and reports of Israeli attacks on Evin prison, where hundreds of prisoners, including political dissidents and human rights defenders, are imprisoned.

“Deliberately attacking civilian objects is prohibited under international humanitarian law and would amount to a war crime.”

It also urged prison security forces not to use force or firearms against distressed prisoners.

Qatar has shut down airspace temporarily as part of measures taken amid developments in the region, the Qatari foreign ministry said in a post on X.

The move comes to ensure safety of residents and visitors, the statement added.

The move comes as Iran has threatened to retaliate against the United States after strikes on its nuclear sites.
