U.S. President Barack Obama was being briefed Friday morning with his national security team on the situation of Boston bombings investigation, a White House official said.

Obama, joined by Vice President Joe Biden, convened the briefing at the White House with senior officials in his national security team, including Attorney General Eric Holder, FBI Director Robert Mueller, Chief of Staff Denis McDonough, and National Security Advisor Tom Donilon.

The briefing was a follow-up to the regular briefings that the president received through the night.

The briefing came after an armed showdown and confrontation between police and two suspects occurred in the Boston area overnight.

The FBI and hundreds of state and local police officers are currently conducting a massive manhunt for one of the suspects identified as 19-year-old Dzhokhar Tsarnaev.

The other suspect, reported as Dzhokhar's 26-year-old brother Tamerlan, was confirmed dead at a local hospital with multiple gunshot wounds after the shootout.

Authorities suspended public transportation, including buses, subways, trolleys, commuter trains and boats, in the Boston region during the search.

Police urged people in Watertown, Cambridge and other western suburbs of Boston, as well as some western neighborhoods of Boston, to stay indoors as the search for Dzhokhar Tsarnaev continued.

The violence and manhunt began only a few hours after the FBI released photos and videos of the two suspected bombers, who were seen carrying backpacks as they walked near the marathon finish line.
