Palestinian medical sources said that Israeli army killed early on this morning a Palestinian resident and wounded critically another in northern Gaza Strip.

The sources said the casualties were not identified.

Israeli warplanes hovered yesterday night over different parts of the Gaza Strip, amidst Israeli threats to carry out a ground offensive on Gaza, after a six-month-old ceasefire has been threatened recently.

Last week, Israeli soldiers, manning the Israel-Gaza border line, killed a 35-year-old Palestinian civilian and wounded another.
