JERUSALEM, Feb. 16 -- A total of 15 people injured in a tourist bus explosion in Egypt's Sinai Peninsula Sunday were sent to a hospital in the southern Israeli port city of Eilat for treatment, Israeli media reported.

Five people -- four South Koreans and an Egyptian bus driver -- were killed in the powerful blast that ripped through a tourist bus as it approached the Taba border crossing with Israel, Egypt's Interior Ministry said.

Israeli emergency services evacuated 15 of the 35 injured to Eilat's Joseftal hospital, where they were taken into intensive care.

There were no Israelis on the bus, Israeli police spokesman Micky Rosenfeld said.

Maj.- Gen. Sami Turgeman, head of the Israeli army's Southern Command, ordered that the border crossing be closed until further notice, a security source told Xinhua.

Meanwhile, military forces have been deployed on the Israeli side of the Taba terminal to bolster security.
