Foreign affairs minister Maxime Verhagen is to send his highest political advisor to Tehran in an effort to find out what is happening to the Dutch human rights activist Abdullah Al-Mansouri, arrested 18 months ago on terrorism charges, reports ANP news service.

The minister told MPs on Tuesday that he is very concerned about reports that Al-Mansouri has been sentenced to death and could be executed within days.
Earlier this week, Al-Mansouri’s son, Adnan Al-Mansouri, said he had been informed about the death sentence by a Syrian human rights organisation.
Verhagen said that although the Iranian ambassador in The Hague assured him that no sentence has been passed on Al-Mansouri, Iran has failed to keep agreements in the past. It has not, for example, kept the Netherlands informed of progress in his trial, the minister said.
Verhagen said he has warned the ambassador that undesirable developments in the case would have serious consequences for the relationship between Iran and the Netherlands.
Al-Mansouri, who came to the Netherlands as a refugee and now has Dutch nationality, was arrested in Syria in May last year and extradited to Iran where he is accused of terrorism.
Verhagen told MPs that he has been working on behalf of Al-Mansouri and that his case has also been taken up by the European Union.
On Tuesday evening a total of around 80 people, including MPs from the Socialist party, GroenLinks and the anti-immigration PVV, took part in wakes held for Al-Mansouri in The Hague and Maastricht.
