Days before Iranian president Mahmoud Ahmadinejad is expected to attend a UN General Assembly meeting in New York, terror victims and advocacy groups have stepped up attempts to hinder his seventh visit to the city by pressurizing the hotel in which he is due to stay.

Stuart Hersh, an American citizen severely injured in a 1997 Jerusalem suicide bombing perpetrated by Hamas, served a lawsuit in Manhattan's federal court this week against luxurious Warwick Hotel, in which the Iranian delegation is booked to stay. The Warwick also hosted Ahmadinejad and his delegation during his 2011 trip to New York.

The move comes after a US federal court found Iran liable last year for the 1997 suicide bombing, because the Islamic Republic provided material support and resources to the Gaza terror group. The court ordered Teheran to pay Hersh damages of $12 million plus interest. However, to date Iran has not paid or responded to the judgement.
