JNS.org – The Sinai terrorist group behind the deadly bombing of a bus that killed three South Korean Christian tourists and their Egyptian driver near an Egypt-Israel crossing to Israel threatened more attacks on tourists unless they leave.

In a statement posted on their Twitter account, the al-Qaeda-affiliated Islamic terror group Ansar Bayt al-Maqdis, which claimed credit for the attack on Sunday, told the tourists to leave before their deadline later this week or face more attacks.

“We recommend tourists to get out safely before the expiry of the deadline,” the tweet read in English.

While Islamic terror groups have mainly targeted government forces since the ouster of Islamist President Mohamed Morsi in July 2013, the attack on Sunday against tourists represents a shift in strategy. Egypt’s Red Sea resorts have largely been immune to the violence that has plagued Egypt elsewhere, and are an important source of income for the country.

The group also boasted in a post on a terrorist online forum that one of its “heroes” perpetrated the bombing.

“God helped your brothers in Ansar Beit al-Maqdis to assign one of its heroes to blow up the tourist bus that was heading to the Zionist entity (Israel),” the group said, the Associated Press reported.
