JAKARTA - United States President Joe Biden has confirmed that his party will hold Iranian officials accountable, as well as impose further 'costs', in line with violence by Iranian security forces in dealing with the protests against Mahsa Amini's death.

In a statement President Biden said he was deeply concerned by reports of an intensive crackdown on peaceful protesters in Iran, pledging to provide a swift response.

"This week, the United States will impose further costs on perpetrators of violence against peaceful protesters. We will continue to hold Iranian officials accountable and support the rights of Iranian citizens to protest freely," President Biden said.

Earlier, Iran's supreme leader gave his full support to security forces, to deal with protests sparked by Mahsa Amini's death in detention, comments that could mark tougher measures to quell unrest more than two weeks since he died.

In her first speech discussing the death of the 22-year-old woman, after being arrested for wearing inappropriate clothes, Ayatollah Ali Khamenei said Amini's death "dept. breaks my heart" and calls it a "difficult incident" provoked by Iran's enemies.

"The task of our security forces, including the police, is to ensure the safety of the Iranian nation. Those who attack the police make Iranians powerless against thugs, robbers, and extortioners," Khamenei said.

Iranian authorities have reported many members of the security forces were killed during the unrest, which has escalated to the biggest opposition show against the Iranian government in years, with many calling for an end to more than four decades of ulama rule.

Khamenei said security forces had faced "un just" during the protests.

"In recent incidents, above all security forces including the police and Basij, as well as the Iranian people, were harmed," he said.

"Some people have caused insecurity in the streets," Khamenei said, condemning what he called a planned "collapse", accusing the United States and Israel, Tehran's arch-foe, of regulating the disturbance.

It is known, Amini (22) from Iran's Kurdistan, was arrested on September 13 in Tehran for "inappropriate use" by moral police and died in detention.

Hours after his funeral in the city of Kurdi Saqez on September 17, thousands of Iranians took to the streets across the country. Security forces, including police and volunteers of the Basij militia, have cracked down on the protests. Human rights groups said the death toll was more than 130.
