Explosion heard near Israeli border with Gaza

Palestinian nationalist fighters in the northern Gaza Strip fired a homemade rocket into Israel on
Tuesday, Palestinian residents said. There were no reports
of injuries or damage.
Witnesses reported a large explosion on the Israeli side
of the Erez crossing, which divides Israel from the Gaza
Strip.
The Israeli army said militants had launched three
projectiles _ either mortars or homemade Qassam rockets _
near the crossing. It gave no details on where the weapons
had landed.
