Washington/Prague, Sep 17 (DPA) US President Barack Obama may scrap plans by his predecessor, George W Bush, to install a missile defence system in Eastern Europe, the Wall Street Journal reported Thursday, citing informed sources.

The White House is to argue the Bush-era project can be halted because Iran has been slower in building long range missiles than previously estimated, the report said.

The report however indicated that the findings of a 60-day White House review of the project are to be concluded next week at the earliest.

Poland and the Czech Republic were due to jointly host the missile project. The Bush administration intended to build a tracking radar in a military base south of Prague and build a launch site with 10 interceptor missiles in Poland.

In Prague Thursday, a spokesman confirmed that Prime Minister Jan Fischer and President Obama spoke by telephone overnight over the issue.

'Barack Obama informed Premier Fischer about the American administration's new position towards the anti-missile shield in Central Europe,' spokesman Roman Prorok said.
