Awwal 24, 1432 / April 28, 2011, SPA -- A roadside bomb hit a bus taking Pakistani navy employees to work in Karachi on Thursday, killing five people in the third such attack this week and just days after the army chief claimed to have "broken the backbone" of militants, as AP reported. The series of attacks in the country's largest city and economic heart show the determination and reach of Al-Qaida-linked extremist networks despite American-backed Pakistani army offensives against their main bases in the northwest close to the Afghan border. The early morning blast mangled the bus and damaged nearby buildings. Four of the dead were sailors, while the fifth was a passer-by, said navy spokesman Salman Ali and Seemi Jamali, a doctor at the city's Jinnah Hospital. Five people were wounded.
