The Department of Foreign Affairs and Trade (DFAT) is seeking to confirm reports that a fourth Australian has been arrested in Yemen. Three men from New South Wales, two of whom are brothers, were arrested about two weeks ago for allegedly trying to smuggle weapons to Islamist militia in Somalia. The Australian Consul in Riyadh was to have met with the men last night but was denied access by Yemeni officials. He is expected to meet them later today. In September, Yemen said it had broken up an Al Qaeda-linked cell that was behind foiled attacks on oil and gas installations.
