American consular services in Israel announced, Monday that "U.S. citizen employees of the U.S. Embassy and the U.S. Consulate General and their families are temporarily prohibited from using sheruts, the mini-bus shared taxis. The temporary prohibition on sheruts is in effect for the next two weeks as we assess the security implications of the December 22 bomb attack on a public bus in the Bat Yam neighborhood of Tel Aviv [sic]. This restriction is in addition to the longstanding prohibition on the use of public buses and their associated terminals and bus stops in Israel."
The advisory sent out by the Jerusalem consulate said, "U.S. citizens are encouraged to exercise caution and take appropriate measures to ensure their safety and security. U.S. citizens should pay close attention to their surroundings and news reports, and follow the civil defense guidance provided by the Home Front Command."
