Israeli fire has killed four people and wounded 14 in the Gaza Strip over the past 24 hours, Palestinian officials said, even as a fragile ceasefire with Hamas has largely held. Israeli strikes have killed dozens of Palestinians who the army says had approached its troops or entered unauthorized areas in violation of the January truce.

An Israeli air strike killed four Palestinians in Gaza, the territory's civil emergency service said, as Arab mediators and the United States tried to hammer out differences between Hamas and Israel over a January 19 ceasefire agreement.

Israel has killed eight people in the Gaza Strip and five more in the West Bank in the past 24 hours, Palestinian officials have said. It comes as a fragile ceasefire in Gaza between Israel and Hamas - which came into effect on 19 January - largely holds.
