On a solidarity trip to Israel, Rep. Pete King said he and former New York Gov. David Paterson today had to scramble to a shelter in the town of Ashkelon near Gaza when sirens warned of incoming Hamas rockets.But Israel's Iron Dome missile defense system, underwritten by U.S. funds, identified and exploded the rockets, King said, creating loud thuds and puffs of smoke in the clear blue sky.King, a Seaford Republican, and Paterson, now the chairman of the New York State Democratic Party, are on a two-day trip to Israel sponsored by the New York Board of Rabbis.The Hamas shelling occurred before Israel and Palestinian militants in Gaza announced they had agreed on a long-term cease fire after seven weeks of fighting, King said."I think it is an open ended cease fire," he said.
