Darfur rebel leader vows more attacks

Khartoum: Darfur rebel leader Khalil Ibrahim said on Monday he would launch more attacks on Sudan's capital Khartoum until the government fell.

"This is just the start of a process and the end is the termination of this regime," said Ibrahim, whose Justice and Equality Movement (JEM) was blamed for an attack in Khartoum.

"Don't expect just one more attack. This is just the beginning," Ibrahim said.

The Sudanese government has accused Ibrahim of masterminding the recent rebel attack in Khartoum. It urged citizens to alert authorities if they see Ibrahim.

Meanwhile, Sudan heightened its security, with a curfew still in force and military checkpoints set up. Security forces were arresting mostly young men who looked to be from Darfur.

The government also arrested Islamist opposition leader Hassan Al Turabi and four top members of his party on Monday, aides said.

JEM leaders were supporters of Turabi in the past. No immediate comment was available from the government on Ibrahim's vow of more attacks and Turabi's arrest.
