US says 4 killed in fourth drug boat strike in a week

The US military said Tuesday that four people had been killed in a strike on another alleged drug-trafficking boat, the fourth such deadly attack in as many days. The four new fatalities raise the total death toll of the controversial military campaign to at least 174, according to a tally compiled by AFP. Two people were killed in a strike on Monday, while SOUTHCOM said two strikes on Saturday had killed five people and left one survivor.
