What is the world turning into, especially the United States? I think it is time the gun laws in US are subject to review.

The numerous recent gun related incidents are getting out of hand, planting fear into ordinary people in the States.

The earlier something is done, the better…

According to DailyMail;

Terror visited Washington D.C. this morning as two gunmen launched an assault on the Washington Naval Yard killing four people and injuring at least 12.

Witnesses reported at least one man described as an African-American male dressed in military fatigues and armed with an AR-15 assault rifle opening fire upon entering the base at the Naval Sea System Command HQ.

After a frantic three hour manhunt U.S. Navy sources told CNN that two shooters were ‘down’ after a frantic three-hour manhunt.

The attacks came three days after al-Qaeda used the 12th anniversary of 9/11 to call for strikes on America.

Hundreds of SWAT and FBI rapid response units descended on the nation’s capital to deal with the situation which unfolded just before 8.30 a.m. this morning.

Initial reports from the scene are that one of the suspects walked up to the facility, opened fire  and then ran inside the building.

People who were inside the building said the gunman — described as a tall, African-American male — wordlessly sprayed fire from an AR-15 assault rifle.

‘We saw him hold the rifle, and we saw him aim it in our direction,’ said one witness to Fox News

Authorities say a base police officer also was seriously injured.

One victim was reported to have been shot on the roof of a building, reported News4′s Tony Tull.

A U.S. Park Police helicopter lowered a basket to a building and lifted what appeared to be a shooting victim from the roof just before 10 a.m.

SWAT officers, military police, U.S. Capitol police and Washington city police all rushed to respond.
