We analyze the 6.4 keV line and continuum emission from the molecular cloudSgr B2 and the source HESS J1745-303, which is supposed to be a complex ofmolecular gas. From the HESS results it follows that Sgr A is a source of highenergy protons, which penetrate into molecular clouds producing there a TeVgamma-ray flux. We present arguments that Sgr A may also produce a flux ofsubrelativistic protons which generate the 6.4 keV line and bremsstrahlungcontinuum emission from the clouds.
