A Mali official says his country will work with Burkina Faso to fight Islamic extremism in West Africa.

Makan Kone, spokesman for Mali's prime minister, said Monday that the two countries will have joint patrols along their shared border.

Mali's Prime Minister Modibo Keita visited Burkina Faso Sunday and with Burkina Faso Prime Minister Paul Kaba Thieba went to the site where extremists attacked a hotel and cafe on Friday, killing at least 28 people. Thieba said the two countries will share intelligence and resources to counter extremism.
