Israel named al-Qaida as the prime suspect in a suicide bombing at a hotel in Kenya on Nov. 28 that killed 13 Kenyans and three Israelis and a failed attempt to shoot down with missiles an Israeli airliner taking off nearby.

“A specific warning was received recently about plans to attack Jews and Israelis in Prague,” the security source said, without giving details.

The capital of the Czech Republic is a popular destination for Israelis. Its centuries-old Jewish quarter attracts hundreds of thousands of visitors and Jewish pilgrims each year.

The source said Israel has received information from several foreign intelligence agencies warning of al-Qaida plans to target Israelis overseas.

Following the Mombasa attacks, Israel’s Foreign Ministry issued travel advisories warning of potential danger to Israelis in Ethiopia, Eritrea, South Africa, Kenya and certain areas of Thailand.
