Gaza is a "powder keg" at risk of exploding, German Foreign Minister Frank-Walter Steinmeier said on Monday during a visit to the Hamas territory, according to AFP.
The German minister, who arrived in the region on Saturday and held talks with top Israeli and Palestinian officials, called for efforts to rebuild Gaza, which was ravaged by a 50-day war last summer, the third in six years.
But he said it would only be possible if there was a halt to Palestinian rocket fire on civilians in southern Israel.
"I came out of all my discussions yesterday in Jerusalem and in Ramallah with the hope that all parties are mindful that here we are sitting on a powder keg here and that we must ensure that the fuse does not catch light," Steinmeier said.
"We shall only be able to decisively reduce the risks of a fresh escalation if we allow economic development in the Gaza Strip in addition to humanitarian aid and reconstruction," he said on a visit to Gaza City's fishing port.
That would only be possible "with open borders" - a reference to the tough restrictions on the movement of goods and people that have been imposed by Israel and Egypt due to the steady flow of Hamas terrorism and arms smuggling.
"But none of this will succeed until it is certain that there will be no further rocket attacks from here, when it is no longer a launch pad," he said.
During his visit, Steinmeier toured a German-funded girls school in the beachfront Shati refugee camp in Gaza City.
But he did not meet any officials from Hamas, the de facto power in Gaza that is designated by the European Union as a terrorist organization.
