The fighting in Lebanon enters its second day as Hezbollah battles pro-government Sunni groups in Beirut. Hezbollah leader Hassan Nasrallah vowed to fight. “Those who try to arrest us, we will arrest them. Those who shoot at us, we will shoot at them. The hand raised against us, we will cut it off,” he said. The government said Hezbollah’s telecommunications network is illegal, which prompted Nasrallah to say “the decision is tantamount to a declaration of war.”
