Hajjaj Saadi, who was handed five death sentences, complained shortly before his execution that he had not been given any assistance from the Egyptian government, a witness said.
Saadi strongly denied in court that he had committed any of the crimes, which shocked the Kuwaiti public, and insisted his confessions were extracted under duress.
Arrested in July 2007 as he prepared to board a flight to Luxor in Egypt, he became known as "the Hawalli monster" for the district near Kuwait City where the crimes took place.
The authorities said Saadi had confessed to raping 17 boys and girls after luring them onto rooftops in Hawalli, an area mainly inhabited by foreigners.
