Sudan conflict: Air strikes and clashes as new ceasefire begins
More air strikes and clashes have been reported in Sudan, dampening hopes for the latest attempt at a ceasefire in the conflict-hit country.
A new seven-day truce officially began at 21:45 local time (19:45 GMT).
But witnesses have already spoken of further hostilities in the capital, Khartoum, and elsewhere.
The violence began five weeks ago, triggered by a power struggle between the leaders of the regular army and a paramilitary faction.
Previous attempts to achieve a lasting pause in hostilities in the north-east African country have been shaky or collapsed.
