French President Nicolas Sarkozy wrote a letter to Prime Minister Binyamin Netanyahu expressing his "sincerest condolences" over the murder of four French Jews in Toulouse on Monday."Like all the citizens of France and all the citizens of Israel, I was shocked and outraged when I was informed this morning on the murder of four people, among them three children, at the Ozar Hatorah school in Toulouse," Sarkozy wrote. Noting that some of the victims were also Israeli citizens, Sarkozy wrote "to impart to you and the entire nation of Israel my sincerest condolences." All four of the victims will be buried in Israel at the request of their families.He also promised to arrest the "despicable" criminal behind the attacks and use the fullest extent of the law to punish his "cruelty."Sarkozy visited the scene of the crime and participated in a memorial ceremony at a Paris synagogue, where he expressed his determination not to allow such a crime go unpunished."On the occasion of these tragedies, I wish to impart to you my profound sympathy," Sarkozy closed the letter, handwriting "with friendship" above his signature.The letter may help smooth over Sarkozy's somewhat rocky relationship with Netanyahu, which has been cool since the French president was overheard referring to the prime minister as "a liar" in a private conversation with US President Barack Obama.
