Mexican police found 129 migrants crowded into a truck trailer in the eastern state of Veracruz, the National Migration Institute (INM) said in a statement. The migrants were crammed into a trailer in the midst of a heat wave in Mexico this year, where higher-than-normal temperatures reached 45°C (113°F), including in Veracruz, where the truck filled with humans was discovered. Four suspected traffickers were arrested during the action.
