The number of people traveling along the Kumba Mamfe Road in the English-speaking southwest region of Cameroon has drastically dropped. It is along this road that goods from Nigeria are brought into Cameroon and vice versa.
Thirty-two-year-old merchant Takem Ethel said she and her peers suspended business trips between Cameroon and Nigeria after President Biya declared war on separatist groups.
'The number of checkpoints are just unbearable,' said Ethel. 'Since the president announced that he was fighting against terrorists, it is as if he removed his hungry lions called the military from their den. Those who want to be killed can travel. I still have my life ahead, so I will not move.'
Violence in the towns of Mamfe and Eyumojock last week claimed the lives of at least six soldiers and a police officer.
Eyumojock is also the hometown of Julius Ayuk Tabe, the man who said he is the first president of Ambazonia, the state the separatists say they have created.
The government of Cameroon says many fighters were being trained there and across the border in Nigeria.
Residents say most youths have escaped to the bushes to flee the heavy presence of the military.
Nyeke George Likiye, an independent analyst in southwestern Cameroon, said he has written to the national government to complain about the troops.
'They are doing their job in excess proportions,' said Likiye. 'There are some arrests, some unreasonable arrests that are being done, people are being tortured, people are being beaten. This is not correct.'
General Melingui Noma, one of Cameroon's highest-ranking military officers, denied the southwest has been militarized or that soldiers are committing atrocities. The general said he is aware of alleged excesses but insisted the military is there to protect the population.
'We know that if we want to overcome this crisis, we have to make sure the population is with us,' he said. 'How can you go and embarrass and harass people whom you want to take information from? If they cannot give us the correct information, if they cannot tell us the truth of what is happening in the field, you will see that the population will then turn and follow those secessionists.'
Schools have been closed in most of the English-speaking northwest and southwest since November of last year, when lawyers and teachers called for a strike to stop what they believed was the overbearing use of the French language. Violence erupted when separatists joined in and started asking for complete independence.
President Biya has said he is not open to any negotiation on the form of the state and that Cameroon is one country.
