In the middle of June, Palestinian factions intensified bombardment over the city of Sderot with improvised Qassam rockets. Palestinian attacks resulted in 2 Palestinians and 1 Chinese civilian killed by a Qassam, and 2 Israelis were killed. The wave of attacks lessened support for the disengagement plan among the Israeli public. Attacks on Israel by the Islamic Jihad and the al-Aqsa Martyrs' Brigades increased in July, and on 12 July, a suicide bombing hit the coastal city of Netanya, killing 5 civilians. On 14 July, Hamas started to shell Israeli settlements inside and outside the Gaza Strip with dozens of Qassam rockets, killing an Israeli woman. On 15 July, Israel resumed its "targeted killing" policy, killing 7 Hamas militants and bombing about 4 Hamas facilities. The continuation of shelling rockets over Israeli settlements, and street battles between Hamas militants and Palestinian policemen, threatened to shatter the truce agreed in the Sharm el-Sheikh Summit of 2005. The Israeli Defence Force also started to build up armored forces around the Gaza Strip in response to the shelling.
