ISTANBUL—Turkish authorities on Sunday investigated a pair of secondary crashes at emergency sites that killed at least 35 people the previous day. In both cases, first responders tending to earlier collisions were among the dead.
Saturday’s tragedies happened just 250 kilometers (155 miles) apart in southern Turkey. The first happened on the highway between Gaziantep and Nizip when a passenger bus collided with emergency teams that had responded to a crash in Mardin Province, west of Derik.
