Negotiators were trying to clinch agreement on Tuesday on the final details of a ceasefire in Gaza after marathon talks in Qatar, with mediators and the warring sides both saying a deal was closer than ever.

Israeli airstrikes on homes in the Gaza Strip killed at least 17 Palestinians, health officials said Tuesday. Earlier strikes in Gaza killed at least 18 people, including two women and four children, according to local health officials, who said one woman was pregnant and the baby died as well.
