Israel has sealed off on Sunday all crossings on Israel-Gaza borders without advanced notice, said a senior Palestinian official.

Director of Palestinian Crossing Security Salim Abu Safiea told reporters in Gaza that the Israeli side has closed Karni commercial terminal and forced Palestinian workers and merchants out.

Other travel passages like Erez on northern tip of the Gaza Strip, and Sofa cargo crossing in the south have also been closed, according to Abu Safiea.

The ongoing Israel closure on the Gaza Strip would deepen the humanitarian and fiscal crisis the Palestinians are suffering from as food aid from the United Nations was not allowed into Gaza.

"Even humanitarian cases were not allowed out of Gaza through Erez crossing," said Abu Safiea, warning that the continuation of this siege would lead to humanitarian disasters.

The Israeli army said it has received warnings of potential attacks by Palestinian militants against the crossings.
