"The army said the soldier was shot on a motorcycle that another man was driving. The driver, a field worker, was also shot," Xinhua reported.
"Both of them died on the spot. The army is currently undertaking a thorough search of people and houses in the locality. All the entrances to the town have been blocked," a military officer who asked to be anonymous told Xinhua.
The incident happened in the town of Penda Mboko in the French-speaking part of Cameroon, close to the border with Muyuka, a restive English-speaking region in the South West.
Armed separatists have been clashing with government forces in the Anglophone regions of the North West and South West since 2017 to fight for the two regions' independence.
The anglophone crisis started in October 2016 with common law lawyers and teachers presenting corporatist demands and condemning years of marginalisation of Anglophones.
The lawyers said they wanted to frustrate attempts by government to annihilate Common Law practice in favour of civil law in a constitutionally bilingual, bi-cultural and bi-jural Cameroon.
Anglophone teachers joined the strike on November 21, 2016, also citing instances of the marginalisation of the Anglo-Saxon system of education.
Things came to a head on November 21, 2016 when Mancho Bibixy's coffin revolution coincided with the teacher's strike. Days of ghost town have since followed, leading to arrests, kidnappings, extrajudicial killings and arson among others.
Over the past three years, Cameroon’s Anglophone regions have been embroiled in a cycle of deadly violence that has claimed an estimated 2,000 lives and uprooted almost half a million people from their homes.
On May 13, the UN Security Council discussed the humanitarian situation in Cameroon during an informal meeting. This gave momentum to international efforts to address the crisis and an opportunity to consider practical steps for an effective humanitarian response, particularly for the most at-risk people.
Right groups say the Security Council should formally add Cameroon to its agenda as a stand-alone item so it can regularly address the crisis and spotlight the dire humanitarian situation in the country, as well as the grave human rights abuses by all sides.
