After his death she uploaded voice files of his final message on to the internet and said she "probably" uploaded a photo of her late husband with one of them.

Taimour Abdulwahab died in the explosion on December 11 2010 in the Bryggargatan area of the Swedish capital.

Nasserdine Menni, whose age is unknown, is on trial at the High Court in Glasgow charged with conspiring with Abdulwahab and others to further terrorist aims, which included the use of explosive devices in the commission of an act of terrorism directed against members of the Swedish public, with intent to murder them.

The court heard earlier that Abdulwahab emailed audio files to his wife Mona Thwany on the day of his death in which he confessed he was a terrorist and had been to the Middle East for jihad.

She accepted that she had uploaded the files, one in English, a second in Swedish and a third in Arabic, on to the YouTube channel. The jury was shown a link to the English file posted on YouTube, accompanied by a picture of Abdulwahab.

Advocate Depute Andrew Miller asked her: "Do you know how the English version file would come to be accompanied by this photo of your husband. Was it you?"

She replied: "Probably. I don't remember exactly."

Menni is also charged with transferring money to or for the use of Abdulwahab, in the knowledge it would be used for the purposes of terrorism.

It is alleged he conspired with Abdulwahab and others from addresses in Glasgow, Luton, Bedford, Syria, Iraq and Sweden between January 1 2003 and March 8 2011. He denies all of the charges against him.
