Oct 28 (Reuters) - At least six United Nations staff were killed when Taliban militants attacked an international guest house in Kabul on Wednesday.

The attack is the second against the U.N. in Afghanistan this year and the bloodiest it has suffered all year. This year's death toll for U.N. workers is now at least 17, compared to about 34 last year and 42 in 2007.

The most devestating attack took place on August 19, 2003, when 22 people, including the chief U.N. envoy to Iraq, were killed in the bombing of the main U.N. office building in Iraq.

Here is a list detailing some incidents where and when U.N. sites and staff have come under attack this year.

GAZA STRIP, Jan 6, 2009 - The shelling of civilians sheltering at U.N. schools in the Hamas-ruled Gaza Strip during an Israeli campaign of air strikes to stamp out Palestinian rocket attacks from Gaza prompts U.N. Secretary-General Ban Ki-moon to call for Israel to explain the "totally unacceptable attacks". Israel blames Hamas for fighting around U.N. sites.

QUETTA, Pakistan, Feb 2 - One U.N. High Commissioner for Refugees (UNHCR) worker is killed, and another is reported missing, after armed men attack their vehicle as they travel to work in the Pakistani city of Quetta.

DARFUR, Sudan, March 10 - Gunmen ambush U.N. and African Union peacekeepers in western Sudan, wounding four.

The assailants open fire on the UNAMID patrol, intended to stamp out violence against cilivians, as it was returning to el-Geneina, the main town in west Darfur, close to the border with Chad.
