Pakistani workers carry a poster of Pakistan’s former Prime Minister, Nawaz Sharif, on a tractor after a rally in Narowal town near Lahore, Pakistan, Monday, March 2, 2009. Late last month, the Supreme Court banned opposition leader Nawaz Sharif from elected office, triggering violent protests by his supporters. If the political unrest continues, some worry Pakistan’s military may intervene, repeating a pattern that has put the country under military rule for much of its turbulent history.
