A Sudanese opposition party says more than 10 opposition leaders have been arrested ahead of the latest day of protests urging President Omar al-Bashir to resign.
In a statement, the Sudanese Congress Party says security forces "pre-empted" demonstrations by arresting the deputy head of the Umma Party, Mariam Sadiq al-Mahdi; the party's Secretary-General Sara Naqdallah; Communist Party leader Mokhtar al-Khatib, and others.
A Sudanese fruit vendor died in Khartoum Sunday from inhaling tear gas fired at protesters.
Medics and the vendor's family said the 62-year-old resident of Bahari, a northern suburb of the Sudanese capital, died in the hospital after choking on tear gas. The tear gas was fired at scores of protesters quickly after they took to the streets Sunday.
Protests in Sudan began on December 19, when the government increased the price of bread threefold.
Later, police fired tear gas to disperse hundreds who had gathered to march, near the Arab Market area in Khartoum.
Sudan has been rocked by a wave of protests since December calling on al-Bashir, who seized power in a 1989 military coup, to step down. Activists say at least 57 people have been killed, but the government tally stands at 30.
