Some Nigerians in the northeast, have fled the region in the heat of insurgency, seeking refuge and shelter.

At some point Cameroon was a haven.

They have stayed away in the nation waiting for peace to return to their communities.

These refugees have been forced back home to what the United Nation described as 'situations of internal displacement'.

The decision to implement the return was taken despite recent tripartite agreements aimed at ensuring voluntary returns.

A statement from the Office of the UN High Commissioner for Refugees (UNHCR) on Tuesday, said Cameroon forcefully returned more than 2,600 refugees back to Nigerian border villages "against their will".

UNHCR spokesperson, Babar Balogh, said in the statement that the organisation was particularly concerned "as these forced returns have continued unabated".

Balogh highlighted that the governments of Nigeria and Cameroon signed the document with UNHCR in Yaoundé on March 2, 2017.

He said that the forced return of asylum-seekers and refugees was a "serious violation" of the 1951 Refugee Convention and the 1969 OAU Convention, which he said, Cameroon had ratified.

He, however, commended Cameroon for its generosity in hosting more than 85,000 Nigerian refugees but urged it to honour its obligations under international and regional refugee protection instruments.

The spokesman said that refugees had fled violent attacks from Boko Haram and urged that "their access to asylum and protection must be ensured.

"Insecurity persists in parts of north-eastern Nigeria and access to basic services remains limited.

"Most returning refugees find themselves in situations of internal displacement upon return and are unable to return to their places of origin". he stated.

Balogh further said that UNHCR recognised the legitimate national security concerns of the Cameroon Government.
