TBILISI -- Georgian opposition deputy Boris Kakubava Denied Tuesday provoking the death of Security Council Secretary Nukzar Sadzhaya, who committed suicide following a smear campaign, according to the authorities.

"My statements could not have been the cause of this tragedy," AFP quoted Kakubava, who had recently accused Sadzhaya of having organized a series of political killings as saying.

The Security Council chief, a close aide of Georgian President Eduard Shevardnadze, took his life Monday as a result of a campaign of "psychological terrorism" waged against him, his family said.

But Kakubava repeated Tuesday his charges against Sadzhaya, saying he had written proof "implicating a large number of people" in the murders carried out during the 1990s.

Kakubava also cast doubt on the suicide theory and described Sadzhaya's death as a "political intrigue of the president."

A long-standing opponent of Shevardnadze, Kakubava fled the country in 1999 after Parliament lifted his immunity at the request of the state prosecutor who suspected him of involvement in an assassination attempt on the president a year earlier.

Sadzhaya, 62, had denied Kakubava's accusations and continued to enjoy support from Shevardnadze who spoke out on his behalf, calling him a "true patriot."
