JERUSALEM, Oct. 2 (Xinhua) -- The Israeli authorities on Tuesday lifted a gag order on Israel's alleged airstrike against Syrian targets last month as Israeli media confirmed the mysterious attack.

    The Israel Defense Forces (IDF) lifted censorship on the fact that the Israel Air Force had carried out an airstrike against a target deep in the Syrian territory on Sept. 6, Israel's mass circulation the Ha'aretz reported.

    Even though the IDF had lifted the gag order, the IDF still declined to reveal any detail on the strike and its purpose.

    An IDF spokeswoman told Xinhua that there was no information available or comments over the operation, which was reported by Western media as targeting a nuclear facility in northeastern Syria, allegedly built by the Democratic People's Republic of Korea (DPRK).

    But both Syria and the DPRK had vehemently denied any nuclear cooperation.

    In an unusually strict measure, the IDF censor had prevented Israeli media from reporting on the strike, unless the reports were based on revelations in foreign press.

    Israel is still maintaining censorship on the details of the airstrike, including the target, the outcome of the strike, and the decision-making process that led up to it.

    On Sept. 6, the Syrian news agency SANA reported that an Israeli fighter jet had breached the Syrian airspace, flying north-east and breaking the sound barrier.

    Two weeks after the strike, in an interview with Israel's Channel One news, opposition leader Benjamin Netanyahu confirmed the Israeli operation in Syria.

    Netanyahu, former Israeli prime minister, said he was briefed on Olmert's decision to carry out the operation in Syria, and he gave Olmert his backing and congratulated him.
