Bombs Kill 2 American Troops in Afghanistan

Two American service members died following bomb attacks in southern Afghanistan, the military said Wednesday.

June is on track to becoming one of the deadliest months for U.S. and international forces in the nearly nine-year Afghan war. Including the latest deaths, 69 international forces have been killed so far this month, 43 of them American.

The ratcheting violence has been matched in recent days by uncertainty about the military leadership following a magazine article that reported deep rifts between the top commander in the war and the U.S. administration.

Gen. Stanley McChrystal has been summoned to Washington to explain disparaging comments about President Obama and his top aides in the Rolling Stone piece. McChrystal has publicly apologized for the article.

He is prepared to submit his resignation at a meeting with Obama on Wednesday at the White House, CBS News has learned - leaving the decision in the president's hands.

The Americans died Tuesday in separate attacks, said Lt. Col. Joseph T. Breasseale, a U.S. military spokesman. He did not provide further details.

The deadliest month of the conflict for U.S. forces was October 2009, when 59 service members were killed. For NATO forces overall, the deadliest month was July 2009, when 75 troops were killed.
