A United Nations agency declared a state of "emergency" in Gaza City on Thursday, after two days of heavy rains and flooding in the Hamas terror enclave.

"Hundreds of residents in the flooded areas around Sheikh Radwan storm water lagoon have evacuated their homes," UNRWA said, referring to a northern district.

While no casualties have been reported from the flooding, UNRWA said it was supplying "emergency fuel to municipalities, water, sanitation and health facilities."

Robert Turner, its director of operations in Gaza, said the agency was "very concerned about such severe storms this early in the season and on the back of unprecedented damage and destruction," in a reference to Hamas's recent terror war on Israel.

Thousands of Gazans were displaced last December after torrential rain hit the coastal territory, UNRWA said.

"Such devastation exacerbates the already poor humanitarian situation for refugees and non-refugees in Gaza, which is dealing with the aftermath of a recent conflict and an acute fuel and energy crisis," it said.

International donors pledged Gaza $5.4 billion to rebuild after Hamas's summer escalation of attacks on Israel that led to Operation Protective Edge.

Israel has made several concessions to Gaza; just this Tuesday a massive shipment of construction materialswas let into Gaza from Israel, despite clear evidence that Hamas isrebuilding terror tunnels into Israel.

The tensions have continued, with Gaza terrorists firing on an IDF jeep conducting a routine patrol on Thursday.

Responding to the incident, MK Danny Danon (Likud) said "the trickling fire from Gaza returns and we must respond with force. We must not be blinded by the seemingly quiet period which provides Hamas and Islamic Jihad time to renovate their terror infrastructure."
