Hezbollah spiritual leader Sheikh Hassan Nasrallah called on Lebanon to boycott the United Nations tribunal investigating the 2005 assassination of former Lebanese Prime Minister Rafik Hariri.
"I call on every official and every citizen in Lebanon to boycott those investigators and not to cooperate with them ... because all that is being offered to them reaches the Israelis," Nasrallah said, according to SANA, Syria's state-run news agency.
In a statement released later, the tribunal called Nasrallah's remarks "a deliberate attempt to obstruct justice."
"The Special Tribunal for Lebanon will continue to rely on full cooperation by the Lebanese government and the support of the international community in fulfilling its mandate in accordance with its statute," the statement read.
U.N. Secretary-General Ban Ki-moon called "such acts of interference and intimidation…unacceptable," U.N. spokesman Martin Nesirky reported.
Nasrallah's remarks came a day after a group of Lebanese women attacked two U.N. investigators and their Lebanese interpreter at a women's clinic in Ouzai, a southern suburb of Beirut. The women stole several items from the investigators, according to The Associated Press.
Nasrallah said the investigators were infringing on Lebanese sovereignty under the guise of an international investigation.
Tribunal Judge Antonio Cassese warned, "Those who carried out this attack must know that violence will not deter the Special Tribunal for Lebanon, a court of law, from fulfilling its mandate."
