PORT-AU-PRINCE (Reuters) - A truck loaded with rubble from Haiti's earthquake two years ago killed at least 26 people and injured 57 others after its driver lost control of the vehicle in a hilly area of the impoverished Caribbean nation's capital, authorities said on Tuesday. The accident came less than a week after the second anniversary of the quake that killed roughly 300,000 people and leveled much of the capital Port-au-Prince. "Between 26 and 30 people have been killed and 57 injured. We are looking for the driver," said Highway Police chief Will Dimanche after the accident in the Delmas district of the city late on Monday.
