At least 26 people were injured on a China Eastern Airlines flight, including four in serious condition, after the plane hit strong turbulence en route from Paris to Kunming Sunday.

The injured are being treated in two hospitals in Kunming, capital of southwest China’s Yunnan Province after the plane, light MU774, landed safely at 8:50 a.m. Sunday at Kunming Changshui International Airport.

“We felt strong turbulence twice and minor turbulence three times. The process lasted about 10 minutes,” said a passenger surnamed Zhang, who suffered a minor injury and is receiving treatment at Yunnan First People’s Hospital.

A number of passengers were thrown from their seats and some were hurt by falling luggage, causing bone fractures, scalp lacerations, soft tissue injuries and other light wounds, according to the passengers and hospitals.

“We applauded when the plane landed safely. We feel lucky the plane did not crash,” said an injured passenger surnamed Shang.

A Chinese naval fleet sailed out of a port in south China’s Hainan Province Sunday for a scheduled military exercise with the Russian navy in St. Petersburg and Kaliningrad.

The fleet consists of one destroyer, one frigate, one comprehensive supply ship, ship-borne helicopters and marines.

The drill is part of an annual program which aims to consolidate and advance the Sino-Russian comprehensive strategic partnership of coordination, and deepen friendly and practical cooperation between the two militaries.

Code-named the “Joint Sea 2017” drill, it will also improve coordination between the two navies on joint defense operations at sea.

According to consensus reached by the two countries, the two navies are scheduled to hold military drill in waters of the Baltic Sea in late July and then the Sea of Japan and Okhotsk in middle September.

This year’s drill aims to jointly carry out rescue missions and protect the safety of economic activities at sea.

Police in northern China’s Inner Mongolia Autonomous Region have arrested 34 suspects in connection with illegal gun manufacturing and trading, according to regional police.

Police in Ordos city seized 41 hunting rifles, 175 semi-finished guns and a large number of bullets.

In March, police from Ordos City Public Security Bureau found a parcel containing suspected gun parts when inspecting the postal sector, leading to the arrest of a gun buyer surnamed Zhang.

Police continued their investigation and destroyed a gun manufacturing site in Yulin city, Shaanxi Province. A suspect surnamed Xie and his son were arrested and a set of gun making equipment and several guns were seized.

Police recently arrested another 24 gun purchasers in Shaanxi and areas of Inner Mongolia in connection with the case.

China bans the manufacturing and sale of guns, with members of the general public not allowed to own them.

Anyone found guilty of owning a gun can face up to seven years in prison.

Chinese environment authorities will establish a system to prevent and punish environmental data fraud, according to an official.

Since environmental monitoring is an important part of technical support in environment management, the ministry will give administrative penalties to people involved in environmental data fraud and transfer them to judicial organs for investigation if necessary, said the official with the Ministry of Environmental Protection.

Xi’an Intermediate People’s Court in northwest China’s Shaanxi Province Friday sentenced seven people, including the heads of two environmental protection branches, to imprisonments of over one year for falsifying air quality monitoring data.

The court said they interfered in the data collection of air quality, and used cotton to fill sampling instruments to lower pollution data, in February and March 2016.
