Bangladesh has asked Saudi Arabia for a copy of the court verdict that led to the execution of two Bangladeshi nationals in Mecca, after Dhaka said it was not told in advance that the pair would be put to death.

The man and the woman were executed on 14 October. Saudi Arabia's interior ministry said they were convicted of an "indecent act" inside a mosque and sentenced under tazir, the category of punishment left to a judge's discretion in Islamic law. The ministry did not describe the act, but said the sentence reflected the seriousness of the offence and the violation of the mosque's sanctity.

State Minister for Foreign Affairs Shama Obaed Islam told reporters at the foreign ministry on Monday that Bangladesh had formally sought details and was waiting for the verdict. "Once we receive a copy of the verdict, we will be able to brief you more clearly and assess the matter," she said.

She urged people not to draw conclusions from Facebook posts or to spread unverified information. The government, she said, still lacks a full account, including the identities of the two and whether their families had been in touch. No relative had approached the ministry with information, she added.

Saudi authorities periodically send Bangladesh lists of its citizens held in the kingdom. Shama said officials were checking whether the two names appeared on those lists, and described Riyadh's response to Dhaka's request as "very positive".

The Daily Star reported that a list of about 2,500 Bangladeshi prisoners, shared after the consulate general in Jeddah asked for information in September, did include the two names but gave no indication that they had been sentenced to death. The newspaper, citing foreign ministry officials in Dhaka and Riyadh, said the list recorded "adultery" as the alleged offence for one and "ICT" for the other. The consulate had received no request for consular help from either of them.

Bangladesh learned of the executions only after they had taken place. On Sunday the Saudi ambassador in Dhaka was asked to provide details and was handed a physical copy of a note verbale that had already been sent electronically, The Daily Star reported.

The foreign ministry has asked its mission in Saudi Arabia to supply all the information it holds so the government can establish where communication failed. Repatriation of the bodies will be taken up once Riyadh responds.

About three million Bangladeshis live and work in Saudi Arabia, one of the biggest destinations for the country's migrant workers and a major source of remittances. The case has drawn wide attention at home.

Amnesty International says Saudi Arabia has executed around 100 people this year, many of them foreign nationals convicted of drug offences.
