A huge explosion has destroyed the house of a Hamas commander in Gaza in the latest incident of a weekend of suspected Palestinian-Israeli violence.
Hamas has blamed an Israeli air strike for the blast, however the Israeli military denied this. The Palestinians say at least 32 people were injured but that figure remains unconfirmed.
The Hamas commander Ala Adnaf is missing and is thought to have died in the explosion. The victims were taken to the local hospital.
Adnaf is said to have been a known bomb maker and accidental explosions in bomb factories are not unknown.
Earlier Israel confirmed it had launched an air strike against border smuggling tunnels at the Rafah crossing point between Gaza and Egypt.
They claim that was in retaliation for a rocket attack by Gaza militants into the Israeli border community of Sderot. That incident caused damage but no injuries.
The renewed violence after weeks of relative calm have raised concerns of a further escalation, jeopardising a fresh push for direct Israeli-Palestinian peace talks.
