The UN has said 'there needs to be justice' following Israel's double strike on a Gaza hospital which killed at least 20 people, as an initial Israeli military probe said the strike had targeted a 'camera positioned by Hamas'.

Condemnation of the attack, whose victims included five journalists and four health workers, has been mounting, with UK Prime Minister Keir Starmer describing it as 'completely indefensible'.

Later on Tuesday, the Israel Defense Forces (IDF) released its initial inquiry, which identified several 'gaps' for further investigation. This inquiry coincides with a day of nationwide protests in Israel, where demonstrators call for the government to agree to a hostage release deal.

On Monday, the attack on Nasser hospital in Khan Younis saw an initial strike kill at least one person before a second strike hit journalists and rescuers at the scene about ten minutes later. At least 20 individuals lost their lives, including international media personnel.

'This is a shock and completely unacceptable,' said UN human rights office spokesman Thameen al-Kheetan. 'There are many questions about the targeting of journalists, and all incidents must be thoroughly investigated.'

The IDF claims the strike was aimed at dismantling a camera believed to be monitoring their activities, further asserting that six of those killed were 'terrorists'. However, the military did not clarify why a second attack followed shortly after the first.

Propelled by ongoing conflict, protests in Israel have erupted, blocking highways as citizens demand a ceasefire and conditions conducive for the hostage negotiations. Amidst calls for accountability, Israel's military actions in Gaza continue, raising pressing questions regarding international law and the protection of civilian infrastructures.
