The last time the World Health Organisation (WHO) was able to reach Gaza’s Nasser Hospital was on January 29, as the medical complex has been under an Israeli siege for more than a week now, the UN agency’s Tarik Jasarevic told Al Jazeera.

More than 400 people remain trapped at the hospital as nearby roads have also been destroyed. Requests to go there have been denied as fighting intensifies with at least 10 people killed by Israeli forces at the medical centre in Khan Younis city, he said.

“All of this is alarming and we keep calling everyone to protect health facilities, to protect patients and health workers,” Jasarevic told Al Jazeera.
