Israeli soldiers have shot and killed two Palestinians near Khan Younis in the Gaza Strip.
An Israeli military spokeswoman said soldiers on Tuesday "identified two infiltrators" and killed both of them following an exchange of fire.
Witnesses in Gaza said Israeli forces also fired shells, hitting agricultural land. The military spokeswoman, however, said she was unaware of the shelling.
The incident came a day after Israeli troops violently intercepted a Gaza-bound flotilla carrying aid, killing at least 10 pro-Palestinian activists on board.
Overnight, the Israeli military reported the firing of a projectile from Gaza into the western Negev, with no injuries reported.
The Al-Aqsa Brigades, a Palestinian armed group, claimed the launch of the projectile.
In a statement the brigades said they worked in conjunction with the Imad Mughniyeh Brigades, another armed group, to fire two homemade projectiles eastward from the Strip, and a third towards the Kissufim military base.
The statement said the fire was a "response to the Israeli crimes against the Freedom Flotilla".
