A volley of rockets has been fired into southern Israel from Gaza, hours after a unilateral Israeli ceasefire began.
At least four out of seven rockets landed near the town of Sderot, with no reports of injuries. Israel launched an air strike on Gaza in response.
Israeli Prime Minister Ehud Olmert said the latest attacks "again proved that the ceasefire is fragile and it has to be reassessed on a minute-by-minute basis".
