Rebuilding Haiti could cost up to $14 billion, which would make last month's quake the most destructive natural disaster in modern history, the Inter-American Development Bank (IDB) said Tuesday.

The figure for reconstructing homes, schools, streets and other infrastructure in Haiti came in a report by the Washington-based pan-American development bank assessing the damage from the January 12 quake.

The report said the damage was estimated at between $8 billion to $14 billion, which factoring in Haiti's population and economic output, would make it the most destructive natural disaster in modern history.

The IDB assessment came after a 7.0-magnitude-quake leveled parts of the Caribbean nation of nine million, already the poorest in the Americas before the disaster.

The quake killed at least 217,000 people and left the capital, Port-au-Prince largely in ruins.
