Six Palestinians have died in an explosion in a smuggling tunnel under the border between Egypt and the Gaza Strip, medical officials say.

At least 14 were injured in the blast, which is believed to have been caused by a cooking gas cannister exploding.

Palestinians regularly smuggle arms, fuel and goods from Egypt in the face of an Israeli economic blockade.

Egypt is building a huge underground barrier along the Gaza border in an attempt to stop smugglers.

The Israeli and Egyptian blockade was imposed in 2007 after the Islamist movement Hamas took power in Gaza.

In an effort to break the blockade, a convoy of ships carrying up to 10,000 tons of supplies and human rights activists are due to arrive in Gaza on Sunday.
