KIRKUK: In a contest over who has Iraq's toughest job, Tahsin Hamid Yassin would be up there with the prime minister, the judge handling the Saddam Hussein trial, and the American commander of the 160,000 foreign troops based in Iraq.

Mr Yassin heads the property claims commission in Kirkuk, arguably Iraq's most volatile town, a place where there is ethnic tension and the threat of clashes. Already the recipient of two death threats in the six weeks he has been in office, he has the delicate task of settling disputes which go to the heart of who has control of this oil-rich town, Arabs, Kurds, or Turkomans.

"It's a heavy burden but I don't care about the threats," says Mr Yassin, who has several bodyguards outside his office on a street blocked against car bombers by concrete barriers.

Under Saddam Hussein tens of thousands of Kurds were driven out of the villages surrounding Kirkuk. The ruined foundations of their homes can be seen on the hills from the road which straddles the oil pipeline going north-east, symbols of the cordon sanitaire Saddam created between his territory and the autonomous Kurdish areas of northern Iraq.

To change Kirkuk's ethnic balance, he brought in an estimated 300,000 Arabs, mainly Shia Muslims from the south. "Some were given money to settle here, some who were in the Ba'ath party were ordered in, and others were part of the massive security apparatus," Mr Yassin says.

Himself a Kurd, Mr Yassin is a lawyer and technocrat, who remained in Iraq under Saddam working as a personnel officer and manager at the Iraq Petroleum Company. The need to "remedy the injustice" of the Arabization policy was spelt out in the interim constitution, which the US occupation authorities drew up with Iraq's governing council this spring.

But Paul Bremer, the former US overlord, kicked the issue into touch by delaying a budget for the property commission. Kurdish politicians on Kirkuk's council rounded on Mr Bremer when he visited the city last month on a farewell trip with Iraq's president, Ghazi al-Yawer. They warned they could not control the anger of displaced people much longer.

Several thousand displaced Kurds have set up a tented camp in Kirkuk's Shorja district. Others are in what was a sports stadium. They have built shacks on the edge of the pitch and under the terraces, with small brick walls to create privacy, fetid open sewers and metres of dangerous wiring leading illegally from lamp-posts along the main road.

As head of the property commission, Mr Yassin's initial task is to register claims. About 4,000 people have come in so far and he expects the number to increase dramatically as word spreads.

With 28 lawyers and 14 assistants he hopes to solve disputes by mediation or, if that fails, arbitration. Occupants will be compensated from government funds if they can prove they spent money improving the properties Saddam's regime gave them.

Mr Yassin hopes Arabs with government jobs will be helped to get similar positions in the south so they can go home. But he recognizes mediation may not work. "Former Ba'athists have escaped from Kirkuk.

They're afraid, so it's unlikely they'll come for mediation", he says. "If they don't, we'll announce it in the newspapers and after a set time, the case will go to a special court."

The court's main judge, a Kurd, sits with an Arab and a Turkoman. They can decide cases by a two-to-one majority. While the property claims mainly pit Arabs against Kurds, the Turkomans say they are being sidelined.

Each of the three communities claims it is the city's largest as well as oldest, and that the others settled in Kirkuk later. Arabs and Turkomans also say the Kurds in Shorja are not returning refugees but squatters sent from the north to inflate the census due next year. -Dawn/The Guardian News Service.
