RECIFE, Brazil — Days after Air France Flight 447 vanished, an intensive international effort has failed to recover any confirmed wreckage and concern grew Friday about whether searchers were even looking in the right place.

Air France, meanwhile, told its pilots in a memo obtained by The Associated Press that it is replacing instruments that affect flight speed in all its bigger jets. Investigators have focused on the equipment’s possible role in the disaster.

Brazilian officials first reported Tuesday that military pilots had spotted wreckage from Flight 447 scattered across the ocean’s surface, but pieces pulled out Thursday turned out to be unrelated to the plane.

U.N.: New uranium traces found in Syria

VIENNA — The U.N nuclear agency on Friday reported its second unexplained find of uranium particles at a Syrian nuclear site, in a probe launched by suspicions that a remote desert site hit by Israeli warplanes was a nearly finished plutonium producing reactor.

In a separate report, the International Atomic Energy Agency said Iran continued to expand its uranium enrichment program despite three sets of U.N. Security Council sanctions meant to pressure Tehran into freezing such activities.

And it said the growing pace of enrichment is causing it to review its inspection routine so that it can maintain oversight of the process.

Up to 34 reported killed in Amazon land protest

LIMA, Peru — Indians protesting oil and gas exploration on their lands battled police in Peru’s remote Amazon Friday, with authorities and Indian leaders separately reporting nine police and 25 protester deaths.

The violence broke out before dawn as officers broke up a road blockade by some 5,000 Indians in an area called Curva del Diablo — or "Devil’s Curve” — in the northern province of Utcubamba.

Protest leaders said police opened fire from helicopters with bullets and tear gas, while national police director Jose Sanchez Farfan said protesters attacked officers with firearms. He said they also set fire to government buildings.

Nine police officers were killed by gunfire and 45 wounded, said Farfan.

Indian leaders said 25 Indians were killed in the clash, accusing the government of "genocide” in attacking what they called a peaceful protest. Another 50 Indians were injured, 14 of them seriously, said Servando Puerta, one indigenous leader.
