A fresh 4.9-magnitude earthquake rattled northern Venezuela on Friday, days after two devastating quakes left hundreds dead and thousands injured, prompting authorities to tighten access to the worst-hit regions.

The latest tremor struck off Venezuela's northern coast and was felt in the capital, Caracas, as well as the city of Maracay, according to Reuters witnesses.

The European-Mediterranean Seismological Centre (EMSC) measured the quake at magnitude 4.9.

In response to the continuing seismic activity, Interior Minister Diosdado Cabello announced that access to La Guaira state, one of the areas worst affected by the earlier earthquakes, would be restricted from 8 pm local time.

Interim leader Delcy Rodríguez also urged residents to avoid travelling to the disaster-hit region.

Meanwhile, the death toll from the twin earthquakes earlier this week has risen sharply.

Authorities said at least 920 people have been killed, while 3,360 others have been injured. The updated figures were released by National Assembly President Jorge Rodríguez.

Rescue teams continue to search through collapsed buildings, with many families still waiting for news of relatives believed to be trapped beneath the rubble.

Officials warned that the casualty count could increase as recovery operations progress. 'Each person saved is a miracle,' Rodríguez said, highlighting the scale of the ongoing rescue effort.
