WASHINGTON — NATO plans to step up attacks on the palaces, headquarters and communications centers that Col. Muammar el-Qaddafi uses to maintain his grip on power in Libya, according to Obama administration and allied officials.

White House officials said President Obama had been briefed on the more energetic bombing campaign, which included a strike early on Monday on Colonel Qaddafi’s residential compound in the heart of Tripoli, the capital.

United States officials said the effort was not intended to kill the Libyan leader, but to take the war to his doorstep, raising the price of his efforts to continue to hold on to power. “We want to make sure he knows there is a war going on, and it’s not just in Misurata,” said a senior administration official, who requested anonymity in discussing military planning.

The NATO campaign, some officials said, arose in part from an analysis of Colonel Qaddafi’s reaction to the bombing of Tripoli that was ordered by President Ronald Reagan a quarter-century ago. Alliance officials concluded that the best hope of dislodging the Libyan leader and forcing him to flee was to cut off his ability to command his most loyal troops.
