DHAKA: Bangladeshi authorities sacked a prosecutor after he condemned court cases against Nobel laureate Muhammad Yunus as `judicial harassment`, officials said on Friday _ prompting him to reportedly seek asylum at the US embassy with his family.

Yunus, 83, is credited with lifting millions out of poverty, but has fallen out with Prime Minister Sheikh Hasina, who says he is `sucking blood` from the poor.

The 2006 Nobel winner`s troubles began after he mounted a short-lived effort to found his own political party, presenting a challenge to the ruling elite.

He now faces nearly 200 cases and up to six months in prison over labour disputes related to social business firms he set up in an effort to create vital jobs and bring services to the poor.

Last week 160 global figures, including former US president Barack Obama and ex-UN secretary general Ban Ki-moon, published a joint letter decrying the `continuous judicial harassment` of the micro-credit pioneer. The signatories, including more than 100 of his fellow Nobel laureates, said they feared for `his safety and freedom`.

Subsequently, deputy attorney general Imran Ahmed Bhuiyan refused to sign a statement denouncing the letter.-AFP
