WASHINGTON (AFP) - The US Treasury said Tuesday it had blacklisted one of the largest charitable groups in the Palestinian territories alleging it is a front for Hamas which is branded a terrorist organization by Washington.

The Treasury said its blacklisting also affected the Al-Salah Society's director who it named as Ahmad Al-Kurd. The US move cuts the charity off from access to the US financial system.

"Hamas has used the Al-Salah Society, as it has other charitable fronts, to finance its terrorist agenda," said Adam Szubin, a Treasury official.

The Treasury said Al-Salah had received "substantial funding" from Middle Eastern countries, including hundreds of thousands of dollars from Kuwaiti donors.

The Treasury said Al-Salah had helped finance the purchase of land for Hamas, as well as providing funding for kindergartens and commercial stores.

Thus freeing other funds for more overt forms of jihad.
