Israeli tourists in Sinai should return to Israel immediately because terrorists are planning to abduct Israelis from the peninsula, the government's Counter-Terrorism Bureau warned on Thursday.

The agency said it issued the warning because it has received new intelligence indicating that Gaza-based Palestinian terror groups and organizations linked to Al-Qaida in Sinai are planning imminent attacks on Israeli tourists there. The terrorists' primary goal is to kidnap Israelis, the agency added.

While it has issued similar warnings several times in the past, many Israelis ignore them, pressing forward with plans to enjoy a relatively cheap beach vacation.

"The Counter-Terrorism Bureau once again urges all Israelis in Sinai to leave the region immediately and return to Israel," the Prime Minister's Office said in a statement on Thursday.

"The Counterterrorism Bureau asks the families of Israelis in Sinai to make contact with them and inform them of this warning. In addition, the bureau strongly recommends that all those planning to go to Sinai refrain from doing so."

The agency has had a travel advisory in place for Sinai for several years now, but the security situation there deteriorated drastically after last year's Egyptian revolution. Over the past year, two serious cross-border terror attacks have been launched at Israel from Sinai, both by terrorist groups affiliated with Al-Qaida.
