Indian police on Wednesday discovered and defused explosives at Mumbai's main railway station, left by militants who struck the city last week. "This is part of the same consignment which the terrorists had brought on Wednesday night when they were attacking and running helter-skelter, some of the material had been left behind," anti-terrorism chief K.P. Raghuvashi said. The situation was "under control" and a bomb disposal unit had defused the devices, he told a foreign news agency.
