BNK48: A member of the Thai girls group wears a swastika on the eve of Holocaust Remembrance Day

A popular Thai music group caused a scandal after the appearance of one of its members wearing a shirt emblazoned with the swastika flag of Nazi Germany during a rehearsal.

The incident, involving the BNK48 girl group, occurred just two days before International Holocaust Remembrance Day, which is marked by dark ceremonies in other parts of the world, including nations that have hosted the notorious death camps of Adolf Hitler, where six million killed by the Third Reich.

The deputy chef de mission of the Israeli embbady in Bangkok went on Twitter to express his "shock and dismay" at the holding.

"Presenting Nazi symbols on behalf of the singer has hurt millions of people around the world," Smadar Shapira said.

The singer, Pichayapa 'Namsai' Natha, aged 19, apologized in tears for her actions and asked for forgiveness.

She then claimed full responsibility for her ignorance in an apology published on her official Facebook page, according to the daily. Morning House of South China.

"Please, give me some tips so that I can become a good adult in the future … I can not fix the mistake, but I promise you not to let it happen, "Namsai wrote in Thai.

Several fans came to Namsai's defense and blamed the Thai education system, which focuses less on world history than on events in Thailand and Myanmar.

Incidents involving insensitive use of Nazi symbols occur from time to time in Thailand, where the holocaust is little known.
