The death toll in Turkey and Syria, after two earthquakes within hours of each other, could continue to rise significantly, according to the World Health Organization. More than 2,700 people are said to have died in the two countries, with the toll continuing to rise as search and rescue operations continue.
The first earthquake, with a magnitude of 7.8, struck in the early hours of the morning near the city of Gaziantep, in southern Turkey. A few hours later, while people were still searching for survivors in the rubble, there was an earthquake of similar magnitude, 100 km to the north.
The intensity of the tremors also toppled tower blocks and public buildings in northern Syria and was felt as far away as Cyprus and Lebanon. The epicenter of the first earthquake was near Gaziantep, a city of more than two million inhabitants. Many took to the streets as buildings began to shake.
The city's castle, which has stood for more than 2,000 years, was also badly damaged. The hilltop castle was built during the Roman Empire. Recently, it was used as a museum.
The historic Yeni Camii mosque, in Malatya, more than 100 miles from the epicenter, was badly damaged. Its domes collapsed, leaving it exposed to the winter sky. The mosque was destroyed by a major earthquake in 1894 and after reconstruction, was damaged by another earthquake in 1964.
Buildings were reduced to rubble in the Mediterranean port city of Iskenderun, Hatay province.
Collapsing buildings killed more than 810 people across Syria. In the city of Aleppo, the ancient citadel destroyed by a decade of war has been further damaged by the earthquake. In the village of Besnaya – Bseineh, a large block of residential and commercial buildings was reduced to rubble.
