QUOTE
The wreath-laying took place at an event at the Palestinian martyrs’ cemetery in Tunisia during a visit by Corbyn in 2014, a year before he became the party’s leader. There is a memorial to the victims of the 1985 bombing at the cemetery, although it is described as being 15 yards away from where Corbyn was pictured.
A couple of metres behind where Corbyn and the group of people are standing are four graves of senior members of the Palestinian Liberation Organisation, thought to have been behind the Black September group. One of those belongs to Atef Bseiso, the PLO’s head of intelligence, who was assassinated outside a Paris hotel in 1992, and was allegedly killed by the Israeli secret service in revenge for the 1972 attack.
Another is the grave of Salah Khalaf, also known as Abu Iyad, who was the second in command in the PLO at the time of his death and is the most senior Palestinian figure buried in the Tunisian cemetery. Khalaf, who is believed to have been a key figure behind Black September, was killed in Tunis in 1991, alongside two other figures who are also buried in the graveyard.

It's betwen the Netanyahu's version (JC laid the wreath in honor of the 4 key figures of the PLO) and JC's version (in honor of the 1985 victims). Which one would you believe?
