Actor Amber Heard has accused estranged husband Johnny Depp of domestic violence.

A US judge has ordered Depp to stay 100 yards away from Heard.

Heard said in a sworn declaration that Depp threw her mobile phone at her during a fight last Saturday, striking her cheek and eye.

She submitted a picture of her bruised face when she applied for a restraining order on Friday.

Los Angeles Superior Court Judge Carl H. Moor also ruled that Depp shouldn't try to contact Heard.

She filed for divorce on Monday, citing irreconcilable differences and saying the pair separated the day before.

She is seeking spousal support from the Pirates of the Caribbean star, but Depp's response filed on Wednesday asked a judge to deny the request.

Depp's lawyer, Laura Wasser, declined to comment.

Depp is in Portugal for a performance with his band Hollywood Vampires.

"Amber Heard just showed up in court with a bruise on her face claiming Johnny Depp physically assaulted her and she's the victim of repeated domestic violence," website TMZ reported.

"She claims Depp smashed his iPhone on her face," TMZ said

The website also alleges Depp broke "various objects in the apartment".

"She says she was on the phone with a friend during the fight, and when Johnny grabbed her phone she screamed to her friend, 'Call the cops!' The friend called 911 and cops came to the residence," TMZ reported.

"Heard claims after he allegedly hit her, he offered her money to stay quiet, but instead she filed for divorce first thing Monday morning," says TMZ.

It claims Heard also has video evidence.
