Islamabad, Sep 25 (IANS): Pakistan's top military commanders held an emergency meeting Sunday to discuss the "prevailing security situation" in the country, the army said.

The special corps commander's conference was held at the General Headquarters in Rawalpindi to discuss the country's security, Geo News reported.

The session was called at a time when several top US military commanders have directly accused Pakistan's spy agency, the Inter-Services Intelligence, of supporting the Haqqani network for carrying out two attacks on the US embassy in Kabul and US military base in Afghanistan's Wadak province this month.

US Secretary Defense Leon Panetta threatened unilateral action against the Haqqani network and other Pakistan-based militant groups.

Pakistan has angrily reacted to the US statements and warned that Washington could loose an ally if it adopted aggressive posture, Xinhua reported.

Media reports said that the emergency meeting was called Sunday, a weekly holiday in Pakistan, in view of the threatening statement by the US military leaders.

Admiral Mike Mullen, chairman of the US Joint Chiefs of Staff came out with blunt remarks Thursday that ISI supported the Haqqani network in the Sep 13 militants' attack on the US embassy in Kabul and the Sep 11 truck bomb attack on the US military base in Wardak which had injured 70 US soldiers.

Paksitan Army chief General Ashfaq Parvez Kayani had dismissed Mullen's remarks as unfortunate and said Pakistan is neither supporting the Haqqani network nor conducting a proxy war in Afghanistan.

Pakistani Prime Minister Yousuf Raza Gilani Saturday snubbed the US military leaders and said Islamabad is not responsible for the security of the US and NATO forces in Afghanistan. Gilani, in his address to the Islamabad-based diplomats, also regretted attacks on Pakistani border posts by militants from Afghan territory despite the presence of thousands of the US and other foreign forces.
