Indian officials have charged a Pakistani national in connection with the deadly Mumbai attacks last year, a case that could result in an execution and heighten tensions between the nuclear-armed nations. Mohammed Ajmal Kasab, 21, was captured in the early hours of the attacks and jailed ever since. He was charged Wednesday with 12 criminal counts, including murder and waging war against India and could face the death penalty if convicted. Nine other attackers were killed during the three-day siege in November, which left 164 people dead and targeted luxury hotels, a Jewish center and other sites across the city. Special public prosecutor Ujjwal Nikam said he expected the trial to begin in coming weeks and conclude within six months - unusually swift for India, where the legal process can drag on for decades. The trial in India's deadliest terror attack, the 1993 Mumbai bombings that killed 257 people, took 14 years to complete.
