They were returning from covering a Taliban warlord’s surrender to the authorities.

One other travelling in the same car was wounded.”Journalists in the tribal areas have shown their courage and determination to carry out their work under pressure from both armed militants and the authorities”, said the worldwide press freedom organisation, which has worked for more than a year with the Tribal Union of Journalists (TUJ). “This cowardly murder should not go unpunished.”Khan, a cameraman with broadcast news agency APTN and a reporter with Pakistani daily The Frontier Post, and Wazir, reporter with Pakistani Khyber TV, the daily The Nation and German news agency DPA, were killed on 7 February in an ambush near Wana, South Waziristan, south-west of Peshawar.Agence France-Presse correspondent in Wana, Anwar Shakir was wounded. They were returning from Sararogha, South Waziristan where Taliban warlord Baitullah Mehsud had given himself up to the Pakistani authorities.The journalists came under machine gunfire as they neared a Wana hospital. The security forces failed to identify those responsible for the attack, but a top local official said that it had been an attempt to sabotage the peace agreement between the authorities and Baitullah Mehsud.Some 20 Wana journalists are employed by international media to cover news from the region.Since the start of the Pakistani army offensive against armed Taliban and al-Qaeda groups in the Wana region in March 2004, the security forces have almost entirely prevented the press from working in the area.In June 2004, the military arrested Khan and Wazir for attempting to penetrate the banned area near Wana. Some journalists have received death threats from the Taliban.

Several hundred subglacial lakes have been identified beneath Antarctica so far. Their interaction with the overlying ice sheet and their influence on ice dynamics are still subjects of investigation. While it is known that lakes reduce the ice-sheet friction towards a free-slip basal boundary condition, little is known about how basal melting and freezing at the lake/ice interface modifies the ice dynamics, thermal regime and ice rheology. In this diagnostic study we simulate the Vostok Subglacial Lake area with a coupled full Stokes 3-D ice-flow model and a 3-D lake-circulation model. The exchange of energy (heat) and mass at the lake/ice interface increases (decreases) the temperature in the ice column above the lake by up to 10% in freezing (melting) areas, resulting in a significant modification of the highly nonlinear ice viscosity. We show that basal lubrication at the bottom of the ice sheet has a significant impact not only on the ice flow above the lake itself, but also on the vicinity and far field. While the ice flow crosses Vostok Subglacial Lake, flow divergence is observed and modelled. The heterogeneous basal-mass-balance pattern at the lake/ice interface intensifies this divergence. Instead of interactive coupling between the ice-flow model and the lake-flow model, only a single iteration is required for a realistic representation of the ice/water interaction. In addition, our study indicates that simplified parameterizations of the surface temperature boundary condition might lead to a velocity error of 20% for the area of investigation.
