In January 2000, Hezbollah assassinated the man responsible for day to day SLA operations, Colonel Akel Hashem. The Israeli Air Force, in apparent response, on 7 February struck Lebanon's civilian infrastructure, including power stations at Baalbek, Deir Nbouh and Jambour. Eighteen people were reported to have been injured.
