The head of the Lebanese Islamist group Hezbollah has urged his countrymen to boycott the UN tribunal into the 2005 killing of former PM Rafik Hariri.
Sheikh Hassan Nasrallah accused the investigators of sending information to Israel.
He had previously described the tribunal as part of an Israeli plot against Hezbollah.
The tribunal has not yet said who will be indicted.
"I call on every Lebanese official and every citizen to boycott these investigators and not to co-operate with them," said the Hezbollah chief.
"All the information and data and addresses (they get) is sent to Israel".
"From now on, any co-operation with the international investigators will be (considered as) helping them to attack [Hezbollah]," he added, in a video-linked speech broadcast on Hezbollah's al-Manar television channel.
His comments came a day after two tribunal investigators were attacked by a group of angry women at a gynaecology clinic in a Hezbollah-controlled suburb of Lebanon's capital, Beirut.
