Sudan boosts border patrols to curb people smuggling In a bid to flee Eritrea and later make it to Europe, a group of migrants were abducted by Sudanese Bedouin Rashaida tribesmen after they illegally crossed into east Sudan. Sudanese security forces, who have stepped up their patrols along the 600-kilometre (370-mile) frontier with Eritrea in a bid to curb migrant smuggling, freed the group.
