More than 2,000 Additional Marines Deployed to Haiti in an Effort to Address Increasing Violence, Lawlessness Following Earthquake

More than 2,000 US marines are set to join 1,000 US troops on the ground in Haiti, as aid efforts gather pace almost a week after the earthquake.

Their arrival comes amid reports of violence and looting and as UN and US forces pushed back an angry crowd at the airport gates with batons.

UN chief Ban Ki-Moon said he would recommend the UN Security Council boost police and troop numbers by 3,500.

Amid increasing security concerns in Haiti, UN Secretary-general Ban Ki-moon asked the Security Council on Monday to send an additional 1,500 police and 2,000 military troops to help keep law and order in the quake-hit island country.

The security reinforcements are expected to bolster ground support for relief efforts led by the UN Mission in Haiti, known as MINUSTAH, which currently has about 7,000 troops and 2,000 international police around Haiti, including 3,000 in the nation's capital, Port-au-Prince.
