The attack came hours before the Emir of Qatar arrived in Gaza in the first visit by a head of state to the blockaded enclave since it was taken over in 2007 by the Iranian-backed Islamist Hamas movement. Israeli Prime Minister Benjamin Netanyahu said Israel will deliver a strong response to the attack. "We will fight and we will hit them very, very hard," Netanyahu said. The Popular Front for the Liberation of Palestine claimed responsibility for the attack that an Israeli military statement said was carried out against soldiers on a "routine patrol adjacent to the security fence in the central Gaza Strip." The wounded officer was evacuated by helicopter to hospital, the statement added. Aditional reporting by Nudal al-Mughrabi in Gaza; Writing by Maayan Lubell; editing by Crispian Balmer
