Britain's Prime Minister David Cameron and Home Secretary Theresa May have hailed the conviction in New York of radical cleric Mustafa Kamel Mustafa on terrorist charges.

May said in a statement Tuesday the British government worked hard to extradite Mustafa, who was sent to the United States in 2012 after a process that took many years.

She said the radical cleric known for his fiery anti-Western sermons "used every opportunity, over many years, to frustrate and delay the extradition process."

Cameron told BBC he hopes to streamline extradition rules so future cases can be handled more quickly.

Mustafa, known in Britain as Abu Hamza, was found guilty Monday of supporting terrorist organizations and planning to open an al-Qaida training camp in Oregon.

The Egyptian-born Mustafa will be sentenced in September.
