KABUL, September 8, 2008 (AFP) - New York-based rights group Human Rights Watch said in a report Monday that civilian deaths from international air strikes in Afghanistan had trebled between 2006 and 2007.

The numbers had grown from at least 116 in 2006 to at least 321 the following year, it said.

There have been at least 119 civilians killed in US and NATO air strikes so far this year, the group said, adding its figures were based on conservative estimates.

Following is a list of some of the main incidents in which civilians have been killed in international air strikes since 2006.

The numbers are usually disputed with Afghan locals and officials often giving different numbers to those issues by international forces.
