Police in Ghana say they have seized a truckload of weapons believed to be headed to Nigeria, where the government is struggling to contain sectarian violence and protests over rising fuel costs.

Authorities say they found double-barrel guns and ammunition inside a truck marked with the name of a soft drink company. Police say the items were hidden beneath a metal plate in the truck.

The seizure took place in Ghana's capital, Accra, on Tuesday after authorities received a tip.

Police arrested five people, including two Nigerian nationals and three suspects from Ghana.
