RAMALLAH, West Bank – Palestinian President Mahmoud Abbas will take a first procedural step toward seeking U.N. recognition of a state of Palestine when he addresses the General Assembly in late September, but has not decided when to ask for a vote on his request, the Palestinian foreign minister said Saturday.

Timing is seen as crucial in the Palestinian bid to be recognized as a non-member observer state by the U.N. General Assembly, an upgrade they hope will firmly establish the West Bank, Gaza and east Jerusalem, captured by Israel in 1967, as Palestinian territories in the eyes of the world.

Some Abbas aides are pushing for quick action, while Abbas is said to be leaning toward waiting until after the U.S. presidential election in November. An earlier Palestinian U.N. bid could add unwelcome complications to President Barack Obama’s re-election efforts.
