BERLIN - German Chancellor Angela Merkel said a UN report that Iran had worked on an atomic weapon design was "alarming" but sanctions had not been fully exhausted as a means of pressuring Tehran, and Germany would consider a tougher round of measures.
In an interview with the Leipziger Volkszeitung published on Saturday, Merkel said opposition to fresh sanctions against Tehran over its nuclear program by some countries was "regrettable".
Russia and China have declared their opposition, limiting the chances of pushing through another UN Security Council package.
"I think the methods we can use to force Iran to be more transparent have not been fully exhausted. Sanctions are first in line here. These sanctions should be as broad as possible," Merkel said.
