Radio and X‐ray observations towards the VHE gamma‐ray source HESS J1813‐178, initially dubbed as a “dark accelerator,” suggested its association with the SNR G12.8‐0.0. Subsequent XMM and Chandra observations confirmed earlier ASCA findings of an extended, center‐filled X‐ray source, not resembling the contours of the radio‐detected supernova remnant (SNR). Morphological and spectral resemblance of the X‐ray emission seen at the center of the shell of SNR G12.8‐0.0 with a Pulsar Wind Nebula (PWN) suggest HESS J1813‐178 is one of the increasing number of objects classified as “composite SNR.” In March 2007, 65 ksec Suzaku observations were taken, and we are able to confirm the previously reported characteristics of the X‐ray counterpart from HESS J1813‐178 as a diffuse hard X‐ray source central to the radio‐shell of SNR G12.8‐0.0.
