The trial opened today of two IRA men and a senior Sinn Fein official who are accused of training Colombian Marxist rebels in terror tactics.

The trial of three Irishmen accused of being IRA activists who trained Colombian rebels was postponed today after they refused to leave their prison cells.

Sinn Fein leader Gerry Adams is today deciding whether to travel to the US to answer questions about alleged links between his party, the IRA and the Colombian guerilla group Farc.
