DAR ES SALAAM—Tanzanian police have arrested 104 suspected Islamic extremists planning to establish bases in neighboring Mozambique, where scores of people have been killed in Islamist attacks over the last year, a senior official said.
Forty attacks have been carried out since October 2017 in Mozambique’s Cabo Delgado province, an area near the Tanzanian border close to where companies are developing one of the biggest natural gas finds in a decade. More than 100 people have been killed, often by decapitation.
