The new 4.8 and 4.7 magnitude quakes struck after 0515GMT in the same zone south of Zagreb that was badly damaged on Tuesday, according to the United States Geological Survey (USGS).
Rescue teams spent the night scouring ruins in the hard-hit area around Petrinja, a town 50 kilometres (30 miles) from the capital, where numerous rooftops collapsed under the force of Tuesday’s 6.4-magnitude quake.
But no new victims were found overnight by the country‘s mountain rescue service, which searched more than 80 villages in the quake-hit zone, the organisation’s chief Josip Granic told reporters.
Among the dead found Tuesday was a young girl struck by falling debris on a street in Petrinja, a man who tried to resuscitate her told local media.
Five men were also killed in a nearby village, local officials said, while another man was buried beneath debris in a church in the village of Zazina, the priest told state news agency HINA.
At least 20 people were injured, Croatian police said.
