A humanitarian catastrophe is unfolding in Lebanon during Israel’s intensified invasion with some aid organisations saying they fear they may have to pull out because of relentless attacks, according to Al Jazeera.

“If the security situation continues to deteriorate, we might have to leave certain areas. There are certain red lines we cannot cross for the security of our teams,” Jeremy Ristord, with medical charity Doctors Without Borders (MSF), told Al Jazeera.

About 40 hospitals in the south are already closed, he noted.

“On top of that, rescue teams are already working under intense strain in adapting their interventions in the face of the degrading security situation,” said Ristord, noting rescuers fear “double-tap strikes” by Israel.

“Sometimes they’re not even able to intervene.”
