Mullah Omar protected Osama Bin Laden in Afghanistan, allowing Bin Laden to plan last year's terrible terrorist attacks on America.
Around 1,500 fighters still loyal to the Taleban are fighting in Afghanistan, but they are surrounded by anti-Taleban forces.
The fighters have said they will hand Mullah Omar over to the opposition if America stops bombing them.
However, there is no evidence to suggest that the Taleban soldiers know where Mullah Omar is.
Peace keeping deal agreed
Also on Friday, an important step forward was taken for Afghanistan.
The country's new leaders agreed to allow a special international army of soldiers, who will help keep the peace.
