Lebanon’s Olympic judo team has refused to train next to Israeli competitors during a session ahead of London 2012.

Olympic officials were forced to erect a special screen at the Excel venue following a complaint from a member of the Lebanese delegation.

It is understood the two squads had been warming up next to each other when the complaint was made on Friday afternoon.

An Israeli official at the venue confirmed a partition had been used to block the view and said the session had then continued with minimum disruption.

He said the Israeli squad had been happy with the original training arrangements but had not objected to the screen being used.

It is not known whether members of the Lebanon team will refuse to compete against Israel’s judo players if they are drawn together during the Olympics.
