Israeli aircraft have scattered pamphlets over the Gaza Strip warning residents to stay away from the border.
The heavily guarded border is the scene of sporadic fighting between militants and Israeli troops. Israeli forces killed two Palestinian fighters in a clash on Friday.
The Arabic pamphlets warn Gazans to stay out of areas 300 meters to 500 meters from the border fence, saying they risk being shot.
The Israeli military had no comment. The military has scattered similar warning pamphlets in the past.
Gaza's Health Ministry says a 10-year-old boy was struck by a box of leaflets and moderately hurt during Monday's airdrop.
Violence has largely subsided in Gaza following an Israeli offensive last January.
