A roadside bomb killed five soldiers from the U.S.-led coalition in Afghanistan on Thursday, The Washington Post reports.

Officials told the newspaper the latest deaths have brought the August toll for the coalition to at least 50, an unusually deadly month.

The exact location of the blast in southern Afghanistan or the identity of the fatalities was not disclosed. The latest incident comes after another NATO soldier also was killed by an explosion in the southern part of the country on Wednesday.

The accident occurred just days after 30 U.S. soldiers, one of their translators and seven Afghan commandos were killed when insurgents shot down their Chinook helicopter.

The helicopter crash was the deadliest in a single incident for the NATO coalition and the U.S. military since the beginning of the military campaign in Afghanistan in 2001. Just over one-third of the way through August, the toll is at least 50.

The NATO-led coalition later managed to kill the Taliban militants responsible for the helicopter attack, after what was described by NATO as an “exhaustive manhunt.”

Violence has persisted in Afghanistan since 2010 and the Taliban has waged a campaign to assassinate top government officials. On Wednesday it was reported that the Taliban has dropped out of preliminary talks with U.S. officials after the discussions were leaked to the press.
