On Thursday morning Gaza residents awoke to destruction caused by overnight Israeli airstrikes that left at least four people dead and wounded around 20 others. In the northern Gaza Strip two people were killed and 10 were wounded, including women and children, when a sports facility belonging to Islamic Jihad was hit. In southern Gaza, a strike on smuggling tunnels running under the border with Egypt killed one man, and another was killed in an airstrike in Gaza City. The wounded were being treated at local hospitals. Israeli claims 14 rockets had earlier been launched from Gaza into Israel. The violence disrupts a ceasefire agreed on Monday after five days of intense cross-border violence.
