KABUL -- NATO announced the death of six troops on Wednesday, underscoring the severity of the challenges here as the fate of the top U.S. commander of the military effort hung in the balance.
Two American troops were killed Tuesday in bombings in southern Afghanistan, a U.S. military spokesman said.
Four other service members, including at least one American, were killed Wednesday.
One was killed in a bombing in western Afghanistan, and the other three died in a roadside bombing and a shooting in southern Afghanistan, military officials said.
The nationalities of three of the troops were not immediately disclosed.
The latest casualties raised the death toll for NATO troops to 73 this month, suggesting that June is likely to be the deadliest month of the nearly nine-year war for the U.S.-led international force.
The troops were killed as President Obama was considering whether to fire Gen. Stanley A. McChrystal for remarks published in a Rolling Stone magazine article that were derisive of civilian administration officials.
