The European Union's (EU) High Representative for Foreign Affairs and Security Policy, Josep Borrell, strongly condemned the Israeli military raid in Nuseirat, Gaza, which resulted in the deaths of 274 Palestinians, including children.
Borrell expressed his concern over the situation in a social media post, calling the incident a "massacre of civilians" and demanding an immediate end to the violence.
He also urged US President
Joe Biden to implement his proposed three-stage plan to secure a ceasefire.
Meanwhile, a US administration official confirmed to the Washington Post that a US "hostage cell" had assisted Israeli forces in freeing four hostages held in Nuseirat.
This revelation prompted the Euro-Med Human Rights Monitor to call for an investigation into the use of a US humanitarian aid pier for military purposes.
Borrell's condemnation came after the Israeli military conducted airstrikes and ground offensives in response to rocket attacks from Palestinian militant groups in Gaza.
The violence marked the worst escalation of conflict between Israel and Palestinians since 2014.
The EU and other international organizations have repeatedly called for an end to the violence and urged both sides to return to the negotiating table.
The UN Security Council held an emergency meeting to discuss the situation, with diplomats expressing deep concern over the loss of civilian lives and the potential for further escalation.
The Biden administration has also expressed its support for a ceasefire and has been in contact with Israeli and Palestinian leaders to encourage a de-escalation of tensions.
However, the situation remains volatile, with both sides continuing to exchange fire and civilian casualties mounting.
