Tel Aviv - A rocket hit the southern Israeli resort city of Eilat near the Egyptian and Jordanian borders Thursday, Israeli police said. Rocket launches are rare in this part of Israel and police suspect that it came from Egypt's Sinai Peninsula. Explosions were heard after midnight in Eilat, a popular tourist destination on the Red Sea that is getting set to welcome thousands of visitors for the Passover holiday. Police spokesman Micky Rosenfeld said no one was injured in the attack and that police were searching for other rockets that may have landed in the city. There was no immediate claim of responsibility. Rosenfeld said the rocket was likely fired from Egypt's Sinai Peninsula. Israel has been warning of growing lawlessness in Sinai. Weak policing and difficult terrain may be turning the peninsula into the latest focus of Islamic militant activity in the region. Last year, gunmen infiltrated into Israel and ambushed vehicles on a desert highway, killing eight Israelis in a brazen, coordinated attack. Israel accused Palestinian militants from Gaza of crossing westward into Sinai, making their way along the Israel-Egypt border and crossing back eastward into Israel to carry out the attack. That incident suggested that Egypt's political upheaval and the resulting power vacuum allowed Gaza militants with allies in Sinai to open a new front against Israel on its long-quiet frontier with Egypt.
