Official says 2 killed in explosion in Gaza

Gaza health ministry official Dr. Moawiya Hassanain said an Israeli strike Saturday killed the men, including a militant. The Israeli army says it didn't fire at them.

The militant group Popular Resistance Committees says one of the dead was a member. The identity of the other man has not been confirmed.

The conflicting reports highlight growing tensions between Israel and Palestinians as a five-month Gaza truce continues to unravel since last week. The fighting has killed 12 Gaza militants. Some 140 rockets, missiles and mortars have been fired from Gaza at Israel.
