Mariame Dia does not know how old she is but her worn eyes have seen enough for a lifetime.
The faces of the policemen who turned her out of her home. The despaired looks on her children's faces as they were forced to cross the river by boat. They have shed tears for the brothers and sisters she was forced to leave behind in Mauritania.
She sits cross-legged and hunched forward, using her red headscarf to wipe the dust from her eyes as she speaks.
“The police found us inside our house, bound our hands and beat my husband. They did not allow us to take anything with us, not even our clothes. Our cattle were left there,” she says.
“They made us cross the river into Senegal without anything."
