Feb 27 (Reuters) - An American woman aid worker and her local driver who were abducted in Afghanistan may have been killed, foreign groups said.

Cyd Mizell, 49, an employee of the Asian Rural Life Development Foundation (ARLDF) and her driver, were kidnapped last month. Following are details of reported kidnappings of foreigners in Afghanistan since 2006.

* March 2006 - Taliban insurgents say they killed four hostages and dumped their bodies in the Kandahar-Helmand area in southern Afghanistan. The four were abducted on March 11. An official at the Ecolog services company in Kabul says the four hostages, all from Macedonia, are its employees.

* April 2006 - An Indian engineer, identified as K. Suryanarayan, is found beheaded on April 30 not far from where he was kidnapped near the main road between Qalat and Ghazni. The Taliban claim responsibility.

* October 2006 - Gabriele Torsello, a London-based photojournalist who is a Muslim, is kidnapped on Oct. 12 by gunmen after he left by bus from Lashkar-Gah, capital of Helmand province in the south. He is released unharmed on Nov. 3.

* March 2007 - The Taliban capture Italian journalist Daniele Mastrogiacomo of La Repubblica and two Afghans in Helmand province. He is handed over to the Italian embassy on March 19 but his Afghan driver is beheaded and his translator is killed on April 8.

* July 2007 - Two German engineers are kidnapped by the Taliban while travelling in Wardak province, southwest of the capital, Kabul. One German is killed, apparently by his captors.
