Israeli warplanes bomb southern Gaza

Israeli warplanes bombed several sites in southern Gaza overnight in response to rocket fire from the Hamas-run enclave, the army and Palestinian medics said on Wednesday.No one was wounded or killed in the strikes, which destroyed an abandoned building in Gaza's only airport, according to medics.The airport was shut down and largely destroyed after the outbreak of the 2000 Palestinian uprising, or intifada, and has not been used since.The attacks came in response to rocket fire from the impoverished enclave over the past several days, the army said in a statement. The rocket fire did not cause any casualties.Israel has repeatedly targeted the vast network of tunnels used to smuggle food and construction materials as well as weapons from Egypt into Gaza, which has been under a punishing blockade since Hamas seized control there in June 2007.Gaza's borders have been mostly quiet since a devastating Israeli offensive in December 2008 and January 2009. Some 1,400 Palestinians and 13 Israelis were killed in the 22-day war.
