The head of the United Nations agency for Palestinian refugees said he feared for civil order in the Gaza Strip after it was hit with a new communications blackout, AFP reports.

“Gaza is again in a total communication blackout, and … it is because there is no fuel,” UNRWA chief Philippe Lazzarini told a press conference in Geneva.

Lazzarini said he was worried that a communications blackout could heighten panic in the Gaza Strip and erode the last traces of public order.
