Egyptian authorities have arrested a Palestinian in the Sinai Peninsula Sunday who allegedly crossed from Gaza to Egypt in one of two recently dug underground tunnels, a security official said Sunday. The two tunnels were uncovered in the Egyptian border city of Rafah. The first tunnel was found by border guards and police in the area, who earlier arrested a Palestinian man in his early 20s as he tried to cross the border in the freshly dug tunnel, the official said. Capt. Mohammed Badr of the North Sinai Peninsula police said after searching the tunnel, police also found water and food inside of it. Another tunnel was discovered inside a residential area in the city of Rafah, Badr said. Security forces did not seal off the second tunnel because they hope to arrest more people trying to sneak into or out of Egypt, he said.
