The Israeli military says it has sent two more warships to the Red Sea border with Egypt following warnings that militants are planning another attack on southern Israel from Egyptian soil.
Earlier this week, Israel's military ordered more troops to the border following intelligence reports of an impending attack.
Israel's home front minister said Tuesday that militants from the Gaza-based Islamic Jihad are in Egypt's Sinai peninsula waiting to attack.
Gunmen who infiltrated Israel through the porous Egyptian Sinai border killed eight Israelis earlier this month.
The attack sparked calls to increase security on both sides of the frontier and created new tensions between Israel and Egypt.
No changes in security alignments were observed on the Egyptian side of the border.
