Plaid Cymru have suspended one of its party members after allegations of anti-Semitism.
Sahar Al-Faifi is reported to have posted anti-Semitic comments on social media which will now be investigated by the party.
The activist says she is willing to be "held accountable" for her past mistakes in an online apology.
Ms Al-Faifi also appeared in Plaid Cymru's party political broadcast, which aired on ITV Wales, BBC and S4C as well as online. The party have since deleted the posts on social media.
A spokesperson for Plaid Cymru said: "We have taken immediate action to suspend the person in question. We will investigate all allegations.
"Plaid Cymru will not tolerate anti-Semitism, racism or intolerance in any form. That includes the appalling abuse the individual has been subject to. It is not a part of the Wales we want to build."
Sahar Al -Faifi, who has been subjected to Islamaphobic abuse herself, has apologised for her posts saying she deeply regrets the her comments and has undertaken anti-Semitism training to ensure she "never repeats the same mistakes."
