“The Mexican army says it has killed 25 suspected drug cartel gunmen in a clash near the US border.

The army said a patrol came under fire as it approached an apparent training camp that had been spotted during an aerial search.

In his state of the union address on Thursday morning, the president admitted the violence was worsening but defended his approach, saying the cartels were being weakened.

“The capture or killing of important criminal leaders has made the crime organizations more desperate,” Mr Calderon said.

“It is an ever more bloody war between organized crime groups fighting for territory, markets and routes … If we want a safe Mexico for the Mexicans of the future, we must take on the cost of achieving it today,” he said.”
