Mexico drug cartels at war

We report on the big drug cartels in Sinaloa state in Mexico. They have made billions from trafficking the deadly drug fentanyl to the United States but have turned their cities into war zones as they compete for dominance of the drug market. It follows news this week of the death of one of the country's most wanted drug lords. Nemesio Ruben Oseguera Cervantes, known as "El Mencho," was killed on Sunday in an operation to arrest him, and his death has sparked a wave of violence right across the land.

Cuba's Interior Ministry has said four people were killed and six others wounded after Cuban border troops engaged in a gunfight near the islands coast.

And United States and Iranian officials are due to meet in Geneva on Thursday for a third round of indirect talks, as President Donald Trump threatens to strike Iran if a nuclear deal is not reached.
