It urged the warring sides to resolve their differences through direct negotiations. \"We will continue to support actions against Palestine,\" it said in a statement, it said. \"We will continue to support the court's decision. \"We will continue to fight against the ICC and the ICC.

The court is not a formal investigation, it allows the court to review evidence and determine whether to investigate suspects on both sides. Prosecutor Fatou Bensouda said her office would \"conduct its analysis in full independence and impartiality.\" The war between Israel and Hamas militants in Gaza last summer left more than 2,000 people dead. The inquiry will include alleged war crimes crimes committed since June. The International Criminal Court was set up in 2002 to prosecute genocide, crimes against humanity and war crimes. "
