French President Nicolas Sarkozy called Israeli Prime Minister Benjamin Netanyahu a "liar" in remarks to US President Barack Obama overheard by journalists.
"I can't stand him any more, he's a liar," Mr Sarkozy said in French.
"You may be sick of him, but me, I have to deal with him every day," Mr Obama replied.
The exchange at the G20 summit was quoted by a French website, Arret sur Images, and confirmed by other media
The remarks - during a private conversation - were overheard by a few journalists last week but were not initially reported, the BBC's Christian Fraser in Paris says...
...It is said Mr Obama was taking Mr Sarkozy to task for voting in favour of the Palestinian bid for full membership of the UN cultural organisation, Unesco, a bid that was approved despite American opposition.
