<p>Former Pakistan Prime Minister Imran Khan was shot in the shin on Thursday when his anti-government protest convoy came under attack in the east of the country in what his aides said was a clear assassination attempt.</p>.<p>Pakistan has a history of political coups and unrest. Here are some details.</p>.<p>2007 - Two-time Prime Minister Benazir Bhutto is assassinated in a gun and bomb attack after holding an election rally in Rawalpindi. A few months before her death, she survives a suicide bomb assassination attempt in Karachi, where at least 139 people are killed in one of the country's deadliest attacks.</p>.<p>1999 - Former army chief Pervez Musharraf seizes power in a bloodless coup. He is sworn in as president and head of state in June 2001. He resigns in 2008 and Asif Ali Zardari, Benazir Bhutto's husband, takes over as president.</p>.<p>1988 - Military ruler President Mohammad Zia ul-Haq is killed when the Hercules C-130 aircraft carrying him crashes in mysterious circumstances. Conspiracy theorists have suggested a case of mangoes put aboard the plane shortly before takeoff contained a timer device that released gas that knocked out the cockpit crew.</p>.<p>1979 - Zulfiqar Ali Bhutto, the father of Benazir who was elected as prime minister in 1970, is hanged on a disputed conviction for conspiring to commit a political murder by Zia ul-Haq.</p>.<p>1977 - Zia ul-Haq seizes power after a coup against the Bhutto government. He puts Bhutto under house arrest, imposes martial law, suspends the constitution and bans political parties</p>.<p>1973 - Zulfiqar Ali Bhutto elected as prime minister, taking over from General Yahya Khan.</p>.<p>1958 - In Pakistan's first military coup, Governor-General Iskander Mirza enforces martial law with General Ayub Khan as chief martial law administrator.
