An Islamic rights group is calling on the International Criminal Court in The Hague, Netherlands, to investigate the government of Bangladesh for alleged crimes against humanity in persecuting its political foes.

British Lawyer Toby Cadman said he had filed the request on behalf of the International Coalition for Freedoms of Rights a month after Bangladesh Prime Minister Sheikh Hasina's party won elections marred by violence and a boycott by the main opposition party.

ICC Prosecutor Fatou Bensouda will decide whether to launch an investigation.

Tejshree Thapa, Asia researcher for Human Rights Watch, said Tuesday the group is concerned about the potential for escalating violence in Bangladesh, but believes government abuses haven't been systematic enough to rise to the level of "crimes against humanity."
