**26 Killed in China Explosion, Bridge Collapse**
At least 26 people have been killed and about 15 injured, when a truck carrying fireworks exploded in central China, causing a bridge to collapse.
State media say the explosion took place Friday in the central province of Henan. They say the truck suddenly exploded as it was crossing an expressway bridge.
Reports say the explosion damaged an 80-meter-long section of the bridge, sending other vehicles plunging to the ground.
**Pemex Blast Kills 25 **
An explosion late Thursday at the Mexico City headquarters of the state-run Pemex oil company has killed 25 people and injured more than 100 others.
Rescuers are searching for people who may still be trapped in the smoldering tower. Helicopters, firefighters and emergency technicians are on the scene.
Video from the Mexican capital showed debris covering the ground and smoke streaming from the lower floors of the scorched building.
There is no word yet on what caused the blast, but officials say equipment problems in the basement may have been responsible.
Mexican President Enrique Pena Nieto visited the site of the blast late Thursday, issued his condolences to the families of the victims, and said he has ordered an investigation.
