The Civil Disobedience Movement commenced with the Dandi March (Salt March). This march started on March 12, 1930, from Sabarmati Ashram, Ahmedabad, Gujarat, and concluded on April 6, 1930, at Dandi, a coastal village. The movement was indeed centered around the issue of the British salt monopoly and tax (Statement 1 is correct). Gandhi deliberately broke the salt law on April 6, 1930, by making salt from seawater (Statement 3 is correct). The event garnered significant international attention and was widely reported by the foreign press (Statement 4 is correct).
