Israeli troops on Saturday killed at least three Hamas militants who were en route to carrying out an attack, throwing an already shaky truce along the Gaza-Israel border further into question. The border clash came just a day after Palestinian President Mahmoud Abbas held rare talks in Cairo with Hamas' supreme leader in exile, Khaled Mashaal, to find ways of rescuing the cease-fire, according to AP. The attempted attack was seen as a snub of both Abbas and Egyptian mediators. -- SPA
