AN INTERNATIONAL AGREEMENT, LEADING TO A CEASE-FIRE IN THE ISRAEL-HEZBOLLAH CONFLICT, IS POSSIBLE SOMETIME IN THE NEXT FEW DAYS, BRITISH PRIME MINISTER TONY BLAIR SAID SATURDAY, ACCORDING TO AP. BUT THE INTERNATIONAL COMMUNITY MUST ACT DECISIVELY AND COLLECTIVELY, BLAIR SAID, AND BOTH ISRAEL AND THE HEZBOLLAH MILITIA MUST AGREE TO END THE VIOLENCE. «I THINK WE CAN GET A U.N. RESOLUTION AND I THINK THAT IF PEOPLE CAN SEE THERE IS A PATHWAY TO A PROPER RESOLUTION, THEN I THINK WE CAN GET A CEASE-FIRE,» BLAIR SAID IN AN INTERVIEW WITH THE BRITISH BROADCASTING CORP. «WE HAVE GOT TO WORK AT THIS VERY HARD OVER THE NEXT FEW DAYS.» BLAIR TOLD THE BBC, «YOU'RE NOT GOING TO GET A CEASE-FIRE ON BOTH SIDES UNTIL YOU PUT IN PLACE THE CONDITIONS THAT ALLOW THAT TO HAPPEN.» THE PRIME MINISTER IS IN THE UNITED STATES TO PROMOTE BRITISH TRADE INTERESTS IN CALIFORNIA, BUT IS CLOSELY MONITORING THE SITUATION IN ISRAEL AND LEBANON. HE ARRIVED IN SAN FRANCISCO AFTER A STOP IN WASHINGTON, WHERE HE MET FRIDAY WITH U.S. PRESIDENT GEORGE W. BUSH TO DISCUSS THE CRISIS IN THE MIDDLE EAST.
