Lebanese Prime Minister Fouad Siniora said on Wednesday he wanted Germany to help arm and train Lebanon's army so that it is able to protect the country from militant groups that threaten its stability.Speaking to reporters in Berlin, Siniora said a key lesson to be learned from Lebanon's 15-week battle against al Qaeda-linked militants of Fatah al-Islam at a Palestinian refugee camp was that an effective Lebanese army was crucial. "It is very important to support the Lebanese army with the necessary equipment, training, methods and ammunition so that it can ... be a deterrent force in the real sense of the word to any group that may think of playing with law and order in the country," he said after meeting German Chancellor Angela Merkel.
