Palestinian men inspect trucks loaded with goods, construction materials and electrical equipments arriving from Israel through the Kerem Shalom border crossing into Rafah, southern Gaza Strip, Monday, Sept. 14, 2010. Israel says it is allowing the largest shipment of construction materials into Gaza since its deadly raid on an international flotilla in May. Israeli military spokesman Guy Inbar says 250 tons of pipes, iron and other materials began to enter Monday to upgrade a Gaza City waste treatment plant. Gaza water official Maher Najjar says the upgraded plant will be able to treat 20 million gallons (75 million liters) of waste a day, nearly double the current level . Photo By Khaled Khaled
