Troops arrest Honduran president

Honduran President Manuel Zelaya has been arrested by troops ahead of a controversial constitutional referendum.

Mr Zelaya's secretary said that the president had been taken to an airbase outside the capital, Tegucigalpa.

Later in the day government supporters blocked the main street outside the gates to the palace.

The move comes days after the president sacked the armed forces chief, who had refused to back the referendum plan.
