Two new expanding X-ray rings were detected by the Swift XRT instrument during early follow-up observations of GRB 061019 and GRB 070129; increasing to 5 the number of dust scattering X-ray halos observed around GRBs. Although these two halos were particularly faint; a sensitive analysis can be performed that optimizes the method originally developed by Tiengo & Mereghetti (2006; A&A; 449; 203) to analyze dust scattering rings observed with XMM-Newton for the Swift satellite. In the case of GRB 061019; a known giant molecular cloud is identified as the one responsible for the scattering process; and its distance is accurately measured (d = 940 ± 40 pc) through the dynamics of the expanding ring. In the second case; XRT observed both the main peak of the prompt emission of GRB 070129 and the scattering halo; but the small number of detected halo photons prevents us from distinguish between different dust models. © ESO 2007;
