Hisham al-Sayed seen lying in bed wearing a mask, with what appears to be an oxygen canister next to him

Gaza’s Hamas rulers have released a video of a captive Israeli citizen held incommunicado since 2015, showing the man lying in a hospital bed wearing an oxygen mask.

It was the first image of Hisham al-Sayed to be released since he wandered across the frontier from southern Israel into Gaza. Its release came a day after Hamas said the condition of one of the Israelis it was holding captive had deteriorated.

Israeli media estimated around 25,000 people took part in contentious annual flag march through Muslim parts of Ohld City

Thousands of Israeli religious nationalists have paraded through Muslim parts of the Old City of Jerusalem, putting the city on edge after violence during the same event last year helped spark an 11-day-war between Israel and Hamas, the Palestinian militant group in the Gaza Strip.

The annual flag march, in which Israelis enter the highly symbolic Damascus Gate and walk through the Muslim Quarter to the Western Wall waving the national flag, takes place around sunset on what Israel calls Jerusalem Day, the celebration of the capture and annexation of East Jerusalem in the 1967 war, a move that is not internationally recognised.

Omar Abu al-Ouf’s father, mother, brother and sister were all killed in the attack on their apartment building last May

Omar Abu al-Ouf is revising for his final school exams, hoping to do well enough to pursue his dream of becoming an engineer, but it’s difficult for the 17-year-old to focus. His mind constantly drifts to his family, all of whom died last year when an Israeli airstrike destroyed their apartment building in a middle-class neighbourhood of Gaza city.

“It’s like he goes somewhere else,” said his grandmother, Manar, in the living room of the boy’s uncle’s house, where he now lives. “His whole family is gone, for nothing.”

Latest court order raises hopes of verdict in trial of World Vision’s Mohammed El Halabi

Pressure is mounting on Israel to conclude the trial of a Gazan aid worker accused of funnelling relief money to Hamas in a six-year-old case widely derided by the international community as “not worthy of a democratic state”.

Mohammed El Halabi, the head of the US-based charity World Vision’s Gaza office, was detained in 2016 after being accused by Israel’s Shin Bet security service of transferring $7.2m (£5.4m) a year to the Palestinian militant group in control of the Gaza Strip.

Cross-border gunfire earlier on Saturday seriously injured an Israeli soldier and wounded 41 Palestinians

Israeli aircraft struck Hamas sites in Gaza late on Saturday, the military said, in an escalation of hostilities after earlier cross-border gunfire seriously injured an Israeli soldier and wounded 41 Palestinians, including two critically.

The injuries came during a Gaza protest organised by the enclave’s Islamist rulers, Hamas, and other factions in support of Jerusalem, where Palestinian clashes with Israeli police helped spark an 11-day Israel-Hamas conflict in May.
