"Stay strong Croatia! After a powerful earthquake struck this morning, the EU_Commission
is in contact with Prime Minister Andrej Plenkovic and the Croatian authorities. We are following the situation closely and stand ready to help," she tweeted.
Plenkovic thanked von der Leyen and the Commission, saying that Croatia appreciated their support.
"It will be vital as we work to rebuild Sisak, Petrinja and the Sisak-Moslavina County, just as we also cooperate on reconstructing Zagreb after the March earthquake," he tweeted.
Central Croatia between Zageb and Sisak was rocked by a magnitude 5.0 earthquake at 6.28 a.m. Two more quakes struck the Petrinja area around 7.50 a.m., one measuring 4.7 and the other 4.1 on the Richter scale.
