Acting U.S Assistant Secretary of State for Near Eastern Affairs, David Satterfield, showed Lebanese officials photographs and maps of sites used by Hezbollah to produce precision missiles, according to a Al-Hayat newspaper report on Sunday.
In his latest visit to Beirut, Satterfield asked the Lebanese government to solve the matter, noting that the U.S. government could neither conceal the findings nor restrain Israel from taking action.
Satterfield's warning is belived to be the reason behind the fiery and defiant speech that Hezbollah leader Hassan Nasrallah gave a few days later.
"It's none of the US business whether we have precision rockets and facilities to produce them or not," Nasrallah said in a televised speech on Friday.
"We don't have factories in Lebanon to produce precision missiles, but if the Americans keep insisting on this issue, we'll establish ones."
