The death toll in Gaza has passed 1,000, Palestinian medical officials say, 19 days after Israel launched an offensive against Hamas militants.

It comes amid a 12-hour humanitarian truce, which Gaza residents have been using to gather essential supplies and retrieve bodies buried under rubble.

Forty-two Israelis have also been killed since the Israel-Hamas conflict began on 8 July.

International talks urging a longer truce were held in Paris on Saturday.

Dozens of bodies have been retrieved from previously inaccessible areas since the truce began at 8am local time.

About 5,870 Palestinians have also been wounded in the 19 days of fighting, health officials say.

The Israel Defense Forces (IDF) said three soldiers were killed in fighting overnight, bringing the total number of Israeli deaths to 40 soldiers and two civilians.

The Israeli military says it will continue to "locate and neutralise" Hamas tunnels during the pause.

Israel launched its military offensive with the declared objective of stopping Hamas firing rockets from Gaza into Israel.

It also began a ground offensive on 18 July, saying it was necessary to destroy tunnels dug by militants to infiltrate Israel.
