Gaza City (CNN) -- Gaza's night skies were illuminated Friday by clashes between Israeli forces and Hamas militants throughout the 27-mile-long Palestinian territory. With fighting reported all along the coastal enclave, casualties poured into Gaza City's Shifaa Hospital, including children, after Israeli artillery shelled east of the city, physicians told the Hamas-run Al-Aqsa TV. The conflict raged for a second night and came after Prime Minister Benjamin Netanyahu warned earlier in the day that ground troops are prepared to expand an offensive against Hamas militants. Palestinian Authority President Mahmoud Abbas will travel Saturday or Sunday to Qatar, "where we're exerting every possible effort in order to do one thing: stop this bloodshed," said chief Palestinian negotiator Saeb Erakat.
