A survey of 29 low-latitude (|b| ⪉ 5°) compact extragalactic radio sources was carried out using the MPI 100-meter radiotelescope and the Jodrell Bank Mk IA radiotelescope as a VLB interferometer at 408 MHz. A major fraction of the sources seen through the inner galaxy (5° ⪉ l ⪉ 60°) did not show fringes, whereas all sources in the zone 190° ⪉ l ⪉ 240° (except one through a major H II region) exhibited significant fringe visibilities with only moderate scattering, if any. The markedly reduced incidence of fringes in sources seen through the inner galaxy is interpreted as due to interstellar broadening. The results are consistent with a model in which heavy scattering occurs in ionized clouds or regions in the inner galaxy having a scale height ≅ 80 pc.
