One million Gazans displaced as Israel readies for ground attack Adel Zaanoun in Gaza with Tim Witcher in Jerusalem, Agence France-Presse

JERUSALEM -- More than one million people have been displaced in the Gaza Strip in the last week, the UN said Sunday, after sustained Israeli bombardment and warnings about a ground attack against Hamas commanders. Israel declared war on the Islamist group last Sunday, a day after waves of fighters broke through the heavily fortified border and shot, stabbed and burned to death more than 1,400, most of them civilians. Seven days of relentless bombing targeting those who masterminded the attack have left more than 2,300 people dead, the majority ordinary Palestinians. But even as Israel seeks to avenge the worst attack in its history, it faced a grave warning about the security implications of putting boots on the ground in the densely populated enclave. "No one can guarantee the control of the situation and the non-expansion of the conflicts" if Israel sends its soldiers into Gaza, said Iran's foreign minister Hossein Amir-Abdollahian. "Those who are interested in preventing the scope of war and crisis from expanding need to prevent the current barbaric attacks... against citizens and civilians in Gaza," he added. Iran is Israel's number one enemy and as well as funding Hamas also backs Hezbollah in Lebanon to the north, where cross-border fire has intensified in the last week. At least 10 people have now been killed in Lebanon and two in Israel, prompting Israel to shut the border area to civilians. Iran has praised the Hamas attacks but insisted it was not involved. However the United States, which has sent two aircraft carriers to the eastern Mediterranean in a show of support for Israel, is wary. In Washington, White House National Security Adviser Jake Sullivan said the United States feared an escalation, particularly the prospect of Iran becoming "directly engaged". US Secretary of State Antony Blinken has in recent days toured Middle Eastern capitals in a frantic round of diplomacy to try to avert a wider crisis in the volatile region. He is due back in Israel on Monday for further talks with Israeli leaders, the State Department said as he arrived in Cairo. Blinken has appealed to China to use its influence in the region to ease tensions. But on Sunday Foreign Minister Wang Yi said Israel's response had "gone beyond the scope of self-defense". He called on Prime Minister Benjamin Netanyahu and his emergency government to "cease its collective punishment of the people of Gaza".
