خليفة بن حمد آل ثاني
In 1985, he plotted a coup against his brother Khalifa bin Hamad Al Thani after he learned that Khalifa had named his own son, Hamad bin Khalifa Al Thani, as the heir. He had his own cache of weapons and maintained a cadre of supporters in northern Qatar. After Suhaim died suddenly of a heart attack in August 1985, his sons blamed Ghanim Al Kuwari, the minister of information and culture, for not responding promptly to his calls for medical attention. They were imprisoned after they attempted to assassinate Al Kuwari.
