Three brothers have been found guilty of supporting terrorism in a US court in Dallas, Texas.
The men were charged with passing money to an official in the militant Palestinian group, Hamas.
Ghassan, Basman and Bayan Elashi were tried on 21 counts of conspiracy, money laundering and dealing in the property of a terrorist.
They will be sentenced later, after one of the US government's highest profile terrorism prosecutions.
Ghassan and Bayan Elashi were convicted on all 21 counts, while Basman Elashi was found guilty on three counts.
Prosecutors said the men tried to conceal a $250,000 investment in their computer firm by an alleged official with Hamas, Mousa Abu Marzook.
Ten years ago he was accused of being a terrorist by the US government.
He was deported and is now believed to be living in Syria.
This effectively meant that it would be illegal for anyone to do business with him - something the Elashi brothers have now been found guilty of.
Last year the three, along with two other Elashi brothers, were convicted of making illegal technology shipments to Libya and Syria - countries the US government considers state sponsors of terrorism.
