Police in Mexico have seized an anti-aircraft machine gun in the state of Sonora, near the US border. They also found ammunition and other heavy weapons. A woman has been arrested.

The seizure took place two days before US President Barack Obama is due to visit his Mexican counterpart, President Felipe Calderón. High on the agenda of the talks between the two will be the bloody drug war currently being waged, mainly with US weapons, by the Mexican drug cartels.

Mr Calderón has made ending the drug war the spearhead of his term in office. US Secretary of State Hillary Clinton has promised him both financial and material aid to accomplish his goal. It is also in the interests of the US to curb the violence of the drug gangs as it often spills over the border into the United States.
