LONDON/TRIPOLI

(Reuters) - President Barack Obama warned Libyan leader Muammar Gaddafi on Wednesday there would be 'no let-up' in pressure on him to go, following a second successive night of heavy NATO bombing in Tripoli.

Six loud explosions rocked Tripoli late on Tuesday within 10 minutes, following powerful strikes 24 hours earlier, including one on Gaddafi's complex in which Libyan officials said 19 died.
