WASHINGTON (AP):

Secretary of State Hillary Rodham Clinton is using her second overseas trip to assess Mid-East peace prospects, reconnect with European allies and remind her Russian counterpart that United States efforts to rebuild relations with Moscow have their limits.

She kicks off the week-long tour by attending an international conference in Egypt, where tomorrow she will announce a US pledge of up to $900 million in humanitarian aid for rebuilding of the war-shaken Gaza Strip.

The Palestinians are seeking $2.8 billion. The United States does not recognise the Hamas movement that rules Gaza and will not allow aid money to flow through Hamas.

Move quickly

The pledge conference reflects in part a US effort to move quickly to influence events there, where the Islamic militants of Hamas controlling Gaza are aligned with Iran and opposed to peace talks with Israel. Hamas is at odds with the other Palestinian faction, Fatah, which controls the West Bank and takes a more moderate approach to Israel.

Clinton also will visit Israel to show President Barack Obama's commitment to finding a 'two-state solution' that establishes a sovereign Palestinian state at peace with Israel.

After elections February 10, Israel is operating under a caretaker government. The hawkish Benjamin Netanyahu is attempting to form a coalition government, but the timing and outcome are in doubt.

Expected visitors

Among leaders Clinton would be expected to visit in Israel are Netanyahu and Foreign Minister Tzipi Livni, leader of the centrist Kadima Party, which won one more seat in the election than Netanyahu's Likud. Netanyahu, who opposes moving forward in peace talks with the Palestinians, was asked to put together the next government because he has the support of a majority of the elected lawmakers.

Israel edged closer to a government of hawks and right-wing religious parties Friday after Netanyahu failed to persuade Livni to join a coalition that could help avert a showdown with the Obama administration. Obama has pledged to become 'aggressively' involved in pursuing Mid-East peace.
