LAHORE, Pakistan (Reuters) - About 30,000 Islamists staged a protest on Sunday to condemn the United States and show support for Pakistan's military, which has reasserted itself after a cross-border NATO attack and a controversial memo that has weakened the civilian government.
Speakers included Hafiz Saeed, a fiercely anti-American cleric suspected of links to the group blamed for the 2008 militant rampage in the Indian city of Mumbai that killed 166 people.
Also at the podium was Maulana Sami-ul-Haq, known as the father of the Afghan Taliban, who are fighting U.S.-led NATO forces across the border in Afghanistan.
Pakistan's military was humiliated by the unilateral U.S. special forces raid that killed Osama bin Laden in a Pakistani town in May, facing unprecedented public criticism.
But many Pakistanis rallied behind it after a November 26 cross-border NATO air raid killed 24 Pakistani soldiers, and plunged already troubled ties with Washington to a low point.
The Islamists' show of support for the military will bring more pressure on Pakistan's civilian leaders, especially deeply unpopular President Asif Ali Zardari, who could be damaged by a memo, allegedly crafted by the former U.S. ambassador to the United States, accusing the military of plotting a coup.
"All Islamist organizations stand with the Pakistan army. We will stand together and defeat any conspiracies against Pakistan and the Pakistan army," said cleric Tahir Ashrafi, in an apparent reference to what has become known as "memogate."
"Long live the Pakistan army," chanted the Islamists in the central city of Lahore.
Businessman Mansoor Ijaz, writing in a column in the Financial Times on October 10, said a senior Pakistani diplomat had asked that a memo be delivered to the Pentagon with a plea for U.S. help to stave off a military coup in the days after the bin Laden raid.
Ijaz later identified the diplomat as Husain Haqqani, the then Pakistani ambassador to Washington who denied involvement in the memo but resigned over the controversy.
No evidence has emerged that the military was plotting a coup and the Pentagon at the time dismissed the memo as not credible.
Army chief General Ashfaq Kayani has called for an investigation into the memo. On Monday, Pakistan's Supreme Court is due to start hearings into a petition demanding an inquiry into who was behind it.
Tension between Pakistan's civilian government and military have bedeviled the nuclear-armed South Asian country for almost its entire existence, with the military ruling the country for more than half of its 64-year history after a series of coups.
Haqqani's resignation was seen by many analysts as further weakening the civilian government, which is already beset by allegations of corruption and incompetence.
The military, which determines security and foreign policy, dismisses any suggestion that it might stage a coup but analysts say military intervention could not be ruled out in the event of chaos.
Zardari is in Dubai, resting at his residence after medical treatment which raised speculation that he would resign. The prime minister has said Zardari's condition is improving and he will return to Pakistan.
At the protest, Islamists from dozens of groups and parties waved flags and chanted "the defense of Pakistan is our holy duty."
It was the type of scene that would concern U.S. officials who have called for a harder line against Pakistan to force it to crack down on militancy.
Those demands seem more unrealistic than ever given hostilities after the NATO attack and a new wave of anti-Americanism sweeping Pakistan, a nuclear-armed U.S. ally.
The Lahore rally was hosted by Jamaat-ud-Dawa, the humanitarian wing of militant group Lashkar-e-Taiba, which is banned in Pakistan and blacklisted by the United Nations.
The Lashkar-e-Taiba was accused of being behind the Mumbai attacks. The JuD denies any role in that bloodshed.
