The Israeli intelligence service Mossad has been accused of assassinating a Palestinian man living in Sweden, according to Israeli daily Haaretz.

Mohammad Tahsin Al-Bazam, a former Gaza resident, was found shot in the head in the Swedish town of Limmared on Saturday. His family is believed to have ties to Hamas, prompting Palestinian sources to suspect Israeli involvement in his death.

A statement released on Sunday by the Swedish police confirmed that as yet they could not ascertain a motive for the intrusion.

“Reports said several people wearing masks entered the apartment through a balcony and shot the man inside. They disappeared after the shooting as quickly as they arrived.”

After the shooting Al-Bazam was taken to a local hospital, and then flown to a larger facility in Gothenburg, but died of his injuries.

Al-Bazam’s brother served in Hamas’ military wing and as a bodyguard to the group’s Prime Minister Ismail Haniyeh. His father is currently the spokesman for Hamas’ Homeland Security Office in Gaza, but stated in an interview that his son had been living in Sweden for over a decade and was not involved in political activity.

Hamas believes Mossad to be responsible for the deaths of numerous of its members over the years, including the assassination of a senior member, Mazen Fuqaha in March. Israel has never confirmed or denied reports but states that it reserves the right to fight alleged terrorists even beyond its borders.
