(CBS/AP) KABUL, Afghanistan - Multiple explosions have rocked the eastern part of the Afghan capital early Tuesday, fresh on the heels of President Obama's visit there.

CBS News' Ahmad Mukhtar reports it was an attack on a compound where foreigners stay. As many as 6 people have been reported killed, including a student and a guard.

The police chief said one of the blasts is believed to have come for foreigners fighting off the attackers with hand grenades. The other was apparently a suicide car bomb attack.

Taliban spokesman Zabihullah Mujahid said in a phone interview with CBS News his organization planned and carried out the attacks. Mujahid claimed the attack was a response to Obama's visit to Afghanistan, to show they were capable of striking anywhere, anytime.

"One of our mujahedin detonated his car in front of a military base. Other mujahedin are inside the base fighting. There are very heavy casualties for the enemy," Mujahid also told Reuters in a phone call.

U.S. President Barack Obama left Kabul only hours before the attacks after signing a strategic agreement with Afghan President Hamid Karzai.

In mid-April, Pakistan-based militants carried out a brazen, 18-hour attack on targets in the Afghan capital, including the U.S. Embassy.

Afghan officials said a gunman arrested in the attacks told authorities the simultaneous strikes in Kabul and three other cities were carried out by the Haqqani network, a militant group allegedly linked to Pakistan's spy agency. The attacks killed 11 people -- eight members of the Afghan security forces and three civilians. Thirty-six insurgents were also killed.
