Questions about Mumbai attacks unanswered

Loory: Mumbai, once known throughout the world as Bombay, is one of the five largest cities in the world, with a population of 19 million. But 10 young terrorists held virtually the whole city in thrall, killing more than 170 and injuring hundreds of others. At the same time, there was sectarian fighting between Christians and Muslims in central Nigeria that resulted in the deaths of over 300 people in a dispute over who won a provincial election. In Nigeria, some reports say that mercenary troops from neighboring Niger and Chad were brought in by the Muslims to fight the Christians. Who was responsible in Mumbai? Some reports say that the Pakistani state intelligence agency experts trained the terrorists for a Muslim terrorist organization, Lashkar-e-Taiba, to carry out the Mumbai attack. Is that why Secretary of State Condoleezza Rice and Joint Chief of Staff Chairman Adm. Mike Mullen visited Pakistan?
