Hamas on Thursday said it opposes any ceasefire deal that includes a large Israeli military presence in Gaza, after offering to release some hostages and as the civil defence reported scores of civilians killed across the Palestinian territory.

Talks resume in Qatar as Israeli PM set to hold talks with US president, who has said a deal could be reached this week.

Israel had been weighing whether to proceed with the indirect talks after Hamas gave a "positive" response to the 60-day ceasefire proposal on July 4.
