IDIL, Turkey — A Syrian protester was killed Friday after a Turkish military vehicle ran him over as it drove through an angry crowd of protesters, Kurdish forces and a Syria war monitoring group said.

The death reflects the increasingly complicated situation in northern Syria in the wake of the American decision to pull its troops away from the Turkish border. The decision was followed by a Turkish invasion and a deal between Turkey and Russia to jointly patrol a strip of northeastern Syria along the Turkish border.

Many of the region’s Kurdish residents oppose the Turkish invasion and the patrols, which they say amount to ethnic cleansing of Kurdish-populated border areas.

The man killed Friday was among a group of residents who had chased and pelted a joint Russian-Turkey convoy with shoes and stones, prompting Turkish troops to fire tear gas to disperse the protesters.
