Palestine Press Agency reports that Egypt has frozen Hamas visas and stopped all official communications with Hamas.
Egypt has been getting more and more incensed at Hamas over the past few months for refusing to sign an Egyptian-brokered reconciliation agreement with Fatah. As a result, the Egyptian government has been cracking down on Hamas smuggling of weapons and especially cash, causing a liquidity crisis in Gaza.
More recently, Hamas has been saying bad things about Egypt and leaking secret details about the negotiations, which has infuriated the Egyptians.
