Monday's incident was the first exchange of fire between Gaza-based militants and Israel in several days. Last week, weeks of relative calm were interrupted with a series of rocket attacks toward Israel and retaliatory airstrikes targeting Gaza rocket teams. The fighting killed 10 Palestinians and an Israeli.
The Israeli military says Gaza militants use the area adjacent to the border as a launching ground for attacks and a place to plant explosives and plan abductions of soldiers. It often strikes targets militants operating in the area.
