President Barack Obama has promised the US will stand alongside Mexico in its fight against drug-related violence.
The vow came after talks with President Enrique Pena Nieto in the White House, in which the two discussed the recent disappearance of 43 Mexican students.
The students were believed to have been handed over to a drugs gang. The case sparked protests around Mexico and more were held outside as the leaders met.
Mr Obama called it a «tragic» case and said he supported Mexico’s response.
The US president said his country would be a «good partner» to its neighbour in the fight against drugs and associated problems.
«Our commitment is to be a friend and supporter of Mexico in its efforts to eliminate the scourge of violence and drug cartels that are responsible for so many tragedies inside of Mexico,» he said.
