WASHINGTON, July 14 (Xinhua) -- U.S. Homeland Security chief Jeh Johnson warned on Thursday of possible violence during the upcoming Republican National Convention.

"I am concerned about the prospect of demonstrations getting out of hand," said Johnson here during a congressional hearing. "I am concerned about the possibility of violence."

According to Johnson, some 3,000 personnel from his agency will be dispatched for the security of both the Republican National between July 18-21 in Cleveland, Ohio and the Democratic National Convention slated for July 25-28 in Philadelphia, Pennsylvania.

"I know that there will be at least another 1,000 or so U.S. Government personnel in hand in both places... as well as probably thousands in terms of state and local law enforcement," he added.

The Republican Convention will come at a time when the country was still reeling from series of racially charged shooting incidents which threatened to pit the country's African-American community and law enforcement officials against each other.

During his year-long campaign, Donald Trump, the New York billionaire developer expected to formally accept the GOP presidential nomination, frequently raised eyebrows across the political spectrum after uttering racially controversial words.

Meanwhile, FBI Director James Comey said on Thursday at the same hearing that the authorities were monitoring closely possible acts of domestic terrorism during the two conventions.

"There is a concern anytime there's an event like this that people from across a spectrum of radical groups will be attracted to it," said Comey. Enditem

XINING, Nov. 13 (Xinhua) -- There are now more than 1,400 Przewalski's gazelle, a species even more endangered than the giant panda, living around a lake in northwest China's Qinghai Province, its only habitat.

According to a survey by Qinghai Lake National Nature Reserve, there were 1,464 gazelle living around the lake, around 200 more than the number recorded last year.

He Yubang, with the reserve, said the survey, which was conducted in August, recorded 324 fawns born this year and 1,140 older gazelle, consisting of 445 males and 695 females.

"This is a record high since our surveys began," He said.

Years of protection has seen the gazelle population quadruple in the past 20 years and lowered its status on the International Union for Conservation of Nature Red List of Threatened Species from "critically endangered" to "endangered."

The local government has set up watering places and supplied foraging food in the winter, and dismantled barbed wire fences, once used to restrict the movement of livestock and mark ownership of the grassland.

The sharp, barbed fences have killed many of the gazelle's in the past, as the animals tried to jump them.

The provincial forestry authorities tore down 515,000 meters of fencing or barbed wire across four counties around the lake from 2009 to 2015 and lowering the height of the remaining fences from 1.5 meters to 1.2 meters. Enditem

RIO DE JANEIRO Cheap Damon Severson Jersey , Feb. 24 (Xinhua) -- The 2016 FINA Diving World Cup in Rio de Janeiro concluded last week with Mexican divers winning one gold and one bronze and ranking third at the medal table. Behind those achievements stands a Chinese coach.

In men's 3m springboard finals, Mexican Maruffo Pacheco took first place with a score of 504.40. Jamaican Yona Roshen Knight-Wisdom came second with American Kristian Ipsen third. Ma said she hadn't expected Pacheco to win in the highly competitive event.

"He transferred from 10m platform to 3m springboard after London Olympics. This time he didn't make so many errors compared with other divers," said Ma.

The Diving World Cup is staged at the Maria Lenk Aquatics Center Cheap Steve Santini Jersey , which is also the venue for Olympic diving event. Ma said Mexico has gained all the Olympic berths except women's synchronized 3m springboard. "I hope we can have better results at Rio Olympics."

Due to Espinosa's triumphs, Ma is considered a hero in Mexico, and has been feted by the Mexican president with the Aztec Eagle award. She is so familiar to the Mexican press Cheap Brian Boyle Jersey , that even reporters can pronounce Ma's name with a decent Chinese accent.

Ma spoke highly of Mexico's recent progress in diving. "The country is paying more and more attention to the sport," she said.

Inspired by Espinosa, one of the country's most popular sports stars Cheap Jimmy Hayes Jersey , more and more children in Mexico are going to diving schools, with many parents hoping they can be as successful as her.

"Mexicans are crazy about their idols and love watching sports very much. Espinosa is the most-welcomed star except for soccer stars in the country," said Ma.
