Government officials say most of the deaths were over business, money disputes, extra-marital affairs, and other personal arguments. Bangladesh embassy says none of Bangladesh's nationals were involved in the killings.
More than 400 Bangladeshis have been murdered in South Africa over the past four years because of business and personal disputes within the community, government officials said on Tuesday.
The Bangladesh embassy in Pretoria said none of the South Asian country's nationals were involved in that violence.
Instead, the Bangladesh ambassador revealed most of the deaths were over business and money disputes, extra-marital affairs, and other personal arguments.
A wave of deadly attacks on foreign workers in South Africa in recent weeks has cast a spotlight on the country's record.
The embassy said the bodies of 88 Bangladeshi migrants had already been repatriated this year, and 452 since January 2015.
"Approximately 95 percent of those who died here were murdered, mostly shot dead in their shops," an embassy official said.
'Local hitmen' doing killings
Ambassador Shabbir Ahmad Chowdhury said the number killed could be far higher, as many families do not report the deaths.
"Many are buried here. It is therefore uncertain to tell the exact number of dead," he told AFP news agency.
Chowdhury said most Bangladeshis "hire local hitmen" who carry out killings to settle disputes.
"Quite a lot of Bangladeshis have been shot dead, but we don't report them, let alone seek justice because many of us live here illegally," Abdul Awal Tansen, a top Bangladeshi community leader in Johannesburg, told AFP.
Bangladeshis started migrating to South Africa in the early 2000s and today an estimated 300,000 live there –– many illegally –– making them one of the largest Bengali diaspora.
Bangladesh media has reported how young men pay traffickers up to $12,000 to get to South Africa.
Thousands own grocery shops across the African nation.
'Surge of fortune seekers'
Scores of Bangladeshi-owned shops were attacked in the recent anti-immigrant violence, community leaders said.
"They often see us as their competitors. We are not taking their jobs yet they attack us with guns," one Bangladeshi migrant, Khalil Mia, told AFP.
The high commissioner said the embassy has urged South African authorities to take action against illegal migration and crime.
"They should be more strict on these issues," he said.
A foreign ministry official in Dhaka said despite the murders, a growing number of young Bangladeshis still try to get to South Africa illegally.
"It is hard to stop the surge of fortune seekers," he said on condition of anonymity.
