Israel increases reservists and missile defence Rockets fired from Gaza have hit the southern Israeli city of Ashdod, as the cross border conflict shows no sign of dying down. One destroyed a car and two others landed in a residential area of Israel's sixth largest city. The fourth rocket struck a building. The Israel Defence Force (IDF) says it intercepted an additional four rockets - all headed for Ashdod. Four people were taken to a local medical centre after suffering minor injuries from the attack. This comes on the same day the Israeli cabinet authorised the mobilisation of up to 75,000 reservists. Saturday morning also saw defence around Tel-Aviv beefed up, with the deployment of a fifth Iron Dome anti-missile battery. Three rockets have been fired at Israel's commercial capital over the past two days. Hamas militants claim to have fired over 100 at the city and Israeli military presence in Tel Aviv has been increased. The extra Israeli troops could feed speculation of a possible invasion into Gaza. However, the government says not all the reservists will necessarily be called to actually serve. More than 830 of what has been described as "terror targets" in Gaza have been hit since the launch of Operation Pillar of Defence, according to the IDF.
