UN warns Israel over possible war crime

The UN is again pleading for aid agencies to gain access to Gaza, and warning of possible war crimes.

Ravina Shamdasani, spokeswoman for the UN high commissioner for human rights, says the organisation is "concerned" that the Israeli military's demand that Palestinians move from northern Gaza to the south could amount to the "forcible transfer of civilians - in breach of international law".

If a country is believed to have committed a war crime during conflict, the case can be looked at by the International Criminal Court (ICC) - the Palestinians are members, but Israel is not.

In a statement, Shamdasani adds that attacks on civilians - while attempting to flee the necessary parts of Gaza - must be investigated independently.

She also appeals for the "immediate and unconditional" release of all Israeli hostages, with the latest Israeli reports indicating around 199 are being held.
