BAGHDAD — Islamic State group militants lined up 30 men in western Iraq and shot them dead Wednesday, an official and residents said, the latest mass killing carried out by the group since its advance across the country.

The slayings, on a main street in the town of Hit, targeted Sunnis tribal fighters allied with the government and members of the security forces that the extremists captured, the official and the residents said.

A photograph obtained by The Associated Press showed a line of the men’s bodies by a small pool of blood as onlookers walked by.
