The World Health Organization has accused Israeli forces of striking its main warehouse and staff residence in Deir al-Balah, Gaza, severely disrupting its operations, Firstpost reported.

Airstrikes caused major damage and forced staff and families to flee. WHO said male staff were detained and interrogated, with one still in custody. Director-General Tedros Ghebreyesus has called for the staffer’s release and urged protection for humanitarian workers.

The strikes coincided with Israeli tank advances into southern and eastern Deir al-Balah, where shelling reportedly killed at least three people and injured others, according to Firstpost.
