One of President Barack Obama's first foreign policy challenges will be trying to resolve the conflict between Israel and the Palestinians.
Although Israel's withdrawal from Gaza by Obama's inauguration day was timely, the two sides could go to war again.
Thousands of Hamas supporters proclaimed victory by holding rallies Tuesday.
Israel has also claimed victory, but analysts say the Jewish state ceased fire before reaching its objectives.
Obama has promised to help achieve peace in the region.
Hamas and Israeli leaders are looking for support and are waiting to see how the new U.S. administration will become involved in the conflict.
