ACCRA, Ghana (AP) — An American couple who used their popular blog to chronicle their journey to adopt four children from Ghana were detained and their two biological children placed in a local orphanage over the weekend after authorities suspected them for child trafficking, officials said Tuesday.

Sol and Christine Moghadam from Irvine, California, had traveled to Ghana with their two biological sons after their application to adopt the four siblings had been approved, according to their blog. An adoption agency official said the family was later reunited and the couple cleared to leave the country with their biological children, although their newly adopted kids will need to await their visas.
