Israel has begun sending reserve soldiers to join in the fighting against Palestinians in the Gaza Strip, the military's chief spokesman told the country's Channel 2 News Sunday night, according to dpa. But Brigadier Avi Benayahu refused to say whether the introduction of the reservists indicated that Israel was widening its 16-day-old aggression. The military had begun calling up reserve units shortly after the Israeli operation began on December 27, but before the ground troops entered the salient on the night of January 3.
