Foreign Minister Tzipi Livni said on Friday at the end of a visit to the United States that she expects the Lebanese government to exercise its sovereignty and enforce the weapons embargo on Hizbullah in order to prevent the group from rearming. "Enforcement of the embargo is of crucial importance," Livni told the Associated Press in a telephone interview, adding that "we know Hizbullah is weak now in terms of weapons." The foreign minister said that enforcing the embargo and disarming Hizbullah were "a test for the Lebanese government and the international community."
