Youths angry at the Nigerian government's failure to fight Islamic extremists threw stones Thursday at President Goodluck Jonathan's electioneering convoy in the eastern city of Yola, breaking windows on some of the vehicles. An Associated Press reporter was unable to see if anyone was hurt.

Police used tear gas and whips to disperse the crowd.

Soldiers guarded billboards and posters of Jonathan, who is running for re-election in Feb. 14 elections. Protesters shouted that they should instead be fighting the Boko Haram insurgents blamed for the deaths of some 10,000 people in the past year.

Yola, capital of Adamawa state, is housing tens of thousands of people driven from their homes in the five-year insurgency.
