Saudi Press Agency reported, citing a source in country's Foreign Ministry, that despite the initial agreements, Tehran had denied the access of the Saudi investigators to Iran as part of their joint activities with the Iranian authorities aimed at inspecting the attacked facilities and finalizing all the processes related to the issue.
The source condemned Iran's attitude to such a sensitive bilateral issue reflected in disrespect for the international laws regulating diplomatic relations, the media outlet added.
According to Arab media reports, some 100 suspects were detained by Iran following the incident of whom 13 were subsequently sentenced to imprisonment. Earlier on Tuesday, the Iranian Appeals Court reportedly upheld the sentences for 10 of those convicted.
