Berlin: Syrian President Bashar al-Assad bears "sole responsibility" for the US strike on a regime airbase, German Chancellor Angela Merkel and French President Francois Hollande said in a joint statement Friday.


"After the chemical weapons massacre of April 4 on Khan Sheikhun in northwestern Syria, a military installation of the Syrian regime was destroyed by a US air strike last night," they said. "President Assad bears sole responsibility for this development."
