Troops in Ivory Coast have been patrolling the streets of Abidjan after Monday's attack on a major military base in which 10 people were killed.

In a television broadcast, new Ivorian Prime Minister Charles Konan Banny expressed regret at the violence.
He said the attack is at a time when the country "is engaged in seeking solutions through the path of peace".
Mutinous soldiers told the BBC they rebelled over pay and status, but officials blamed "outsiders".
The fighting comes five days after a new government was named to oversee disarmament and elections in October.
The allocation of ministerial posts followed several weeks of tense negotiations between supporters of President Laurent Gbagbo, opposition parties and rebel forces who control the north of Ivory Coast.
The rebel New Forces movement - which has controlled the northern half of the country for three years - has denied involvement.
Three soldiers and seven attackers were killed, says the army.
The army is reported to have taken over 30 prisoners.
Gunfire and heavy explosions shook two camps at Akuedo - separated by a main road - just outside Ivory Coast's main city for about an hour at dawn on Monday.
Witnesses say explosions shook buildings in Abidjan itself.
Outside Akuedo, two vehicles were burnt-out - one an army pick-up truck.
Several attackers were taken prisoner.
There have been a number of unexplained attacks on barracks in recent months.
A barracks in Abidjan was attacked by unknown gunmen a month ago.
Ivory Coast has been prone to army mutinies for the past five years, some of which have expanded into full-scale coup attempts.
