A tribunal investigating the 2005 assassination of Lebanese Prime Minister Rafik Hariri said Thursday a Hizbullah call for a boycott was a "deliberate attempt to obstruct justice".

Hizbullah chief Hassan Nasrallah urged all Lebanese to boycott the U.N.-backed probe Special Tribunal for Lebanon (STL), warning that cooperation amounted to an attack on Hizbullah.

The United States on Thursday accused Syria and Iran of fuelling tensions in Lebanon with illicit arms supplies, which a top U.N. envoy warned was part of a "hurricane blowing up" in the Middle East.

New fears about Lebanon, where the government faces mounting pressure from Hizbullah, were raised at closed U.N. Security Council consultations in which the U.N. leadership again called for the disarming of "Hizbullah and other militias."

Kuwaiti daily Al-Rai has announced that it will publish Friday "a classified document it obtained," which is allegedly related to Abdul Baset Bani Audeh, a witness in the Hariri case.

According to Al-Rai, the classified document is signed by the international investigation commission into the murder of ex-PM Rafik Hariri.

Israel traded 52 Palestinian and Lebanese prisoners to Hizbullah in exchange for the gun of an Israeli airman who went missing in southern Lebanon in 1986, a newspaper said on Thursday.

Details of the December 2000 deal were revealed by the mass-selling Yediot Aharonot newspaper, which said it was a secret part of negotiations to release three soldiers and a businessman captured in separate incidents that year.

Hizbullah Secretary-General Sayyed Hassan Nasrallah on Thursday called on "every official and every citizen to boycott the work of U.N. investigators" probing the murder of former premier Rafik Hariri.

"I call on all officials to do what their conscience and honor tell them … Enough violations."

Around one hour after Hizbullah chief Sayyed Hassan Nasrallah called on the Lebanese to boycott the Special Tribunal for Lebanon, Lebanese Forces leader Samir Geagea criticized Nasrallah's televised speech, describing it as "very dangerous."

Geagea described Nasrallah's stances as threats against the Lebanese State, noting that the State is "the side mainly dealing with U.N. investigators."
