VIENNA (Reuters) – OPEC talks broke down in acrimony on Wednesday without an agreement to raise oil output after Saudi Arabia failed to convince the cartel to lift production.

“We were unable to reach an agreement — this is one of the worst meetings we have ever had,” said Ali al-Naimi, oil minister for Saudi Arabia, OPEC’s biggest producer.

VIENNA (Reuters) – War in Libya, Qatari support for its rebel army and rivalries between Saudi Arabia and Iran need not scupper OPEC’s attempts to forge a new oil output deal in Vienna.

The 50 year-old group has held together through two Gulf wars involving its members and the protracted, bitter Iran-Iraq conflict that claimed the lives of hundreds of thousands. OPEC oil ministers still sat around the same table.

GENEVA (Reuters) – Direct government intervention may be needed to burst bubbles in commodity markets inflated by a new herd of financial investors, a U.N. study found.

CHICAGO/GENEVA (Reuters) – After 30 years of AIDS prevention efforts, global leaders may now need to shift their focus to spending more on drugs used to treat the disease as new data show this may also be the best way to prevent the virus from spreading.

The U.N. General Assembly will take up the issue next week as it assesses progress in fighting the disease — first reported on June 5, 1981 — that has infected more than 60 million people and claimed nearly 30 million lives.

GENEVA (Reuters) – OPEC could next week agree its first formal increase in supply targets since 2007 when it meets to hammer out its response to Arab world turmoil, extreme market volatility and pressure from the West for action.

One OPEC delegate told Reuters on Thursday the producer group might raise its collective target by as much as 1.5 million barrels per day (bpd) at talks in Vienna on June 8, its first official meeting this year.

GENEVA (Reuters) – A U.N. envoy said on Tuesday the international community as well as Sri Lanka should further investigate horrific footage apparently showing summary executions of naked men and women during Sri Lanka’s civil war.

He stopped short of saying there could be an international war crimes case, but his comments raised pressure on Colombo to submit to an international inquiry into charges that war crimes were committed at the end of its 25-year war with guerrillas of the Liberation Tigers of Tamil Eelam (LTTE).

GENEVA (Reuters) – Trade judges this month overturned parts of a ruling that accused EU states of giving Airbus (EAD.PA: Quote, Profile, Research, Stock Buzz) illegal subsidies, but said the aircraft maker received billions of dollars of unfair aid that harmed Boeing (BA.N: Quote, Profile, Research, Stock Buzz).

Together with a parallel case over U.S. payments to Boeing, the long-running challenges constitute the world’s largest trade dispute, affecting more than 100,000 jobs in a plane market worth more than $2 trillion.

GENEVA (Reuters) – Video footage of summary executions apparently committed during the Sri Lankan civil war is on the face of it convincing evidence of “serious international crimes,” a U.N. special envoy said on Monday.

The charge adds to pressure on Colombo to submit to an international inquiry into allegations thousands of civilians were killed at the end of its 25-year war with the Liberation Tigers of Tamil Eelam (LITE).
