ROME, Aug.26 (Xinhua) — The death toll of the deadly earthquake in central Italy has risen to 267, said Italy's civil protection agency on Friday morning.

Italy has declared a state of emergency in the regions worst hit by Wednesday's earthquake as hopes of finding more survivors fade.

Prime Minister Matteo Renzi has pledged €50m (£42m) in funds for rebuilding.

At least 267 people are now known to have died and 400 were injured. Teams have continued to search the rubble of toppled buildings for a second night.

However, hundreds of aftershocks have hampered the efforts of the 5,000 rescuers.

Another magnitude-4.7 tremor struck early on Friday.
