ANKARA, Turkey — President Recep Tayyip Erdogan slammed Amnesty International on Tuesday for a report alleging that some people detained in connection with Turkey’s failed coup attempt had been tortured.

Erdogan insisted that Turkey had a policy of ‘‘zero tolerance toward torture’’ and accused the ­London-based rights advocacy group of ­ignoring violence committed by the coup plotters during the July 15 attempt.

During a speech to representatives of foreign companies investing in Turkey, he called on Amnesty to visit sites attacked by the plotters.

‘‘If you have any self-respect, you’ll come to Turkey . . . you’ll visit our [wounded] in hospital, and you’ll see who did what to whom,’’ Erdogan said.

Erdogan said some of those detained may have been beaten during scuffles as pro-government forces quashed the coup attempt.

In a statement ­responding to Erdogan, Amnesty said it had ‘‘repeatedly condemned the appalling violence committed by those behind the . . . coup attempt.’’

‘‘At the same time, Amnesty International has urged Turkish authorities to respect the rule of law and the rights of all those detained,’’ Amnesty’s secretary general, Salil Shetty, said.
