MOGADISHU, Jan 4 (Reuters) - Militiamen fired a rocket at an oil tanker truck near Mogadishu on Thursday, wounding several people in the first major attack since government forces took the Somali capital last week, a government source said. "The militiamen wanted to extort money from the tanker (crew)," said the government source. "They hit it with an anti-aircraft rocket. Several people have been wounded."
