Hamas wants Israel to halt all attacks on Gaza and lift tight restrictions on trade and movement in and out of the territory that have been in place since Hamas seized Gaza by force in 2007. Israel demands an end to rocket fire from Gaza and a halt to weapons smuggling into Gaza through tunnels under the border with Egypt.
The widening conflict distracted from Obama's three-country tour of Southeast Asia, his first overseas trip after winning re-election. The president, after a marathon day that took him from Thailand to Myanmar to Cambodia, worked the phones with Mideast leaders into the early hours of Tuesday morning, aides said. He departed Cambodia later Tuesday, and was expected to arrive in Washington before dawn Wednesday.
