Palestinian terrorists in the Gaza Strip on Tuesday claimed they had sent a series of floating bombs toward Israeli beaches, saying the attempted attacks were meant to avenge the mysterious death of a Hamas operative in Dubai last month.
The terrorists claimed additional bombs were still floating in the Mediterranean, and Israeli police cordoned off a swath of the coastline while they searched for more explosives.
Prime Minister Binyamin Netanyahu said Israel would "respond" to the attempted attacks.
Police said two barrels, each containing 22 pounds (10 kilograms) of explosives, washed up on Israel's shores late Monday. A bomb squad defused one barrel, while the second blew up as a police robot prodded it. No one was hurt.
By Tuesday, police were sweeping the entire Israeli coast in jeeps and on horseback. They also shut down a 40-kilometer beach strip near Gaza, ordering surfers out of the water.
