 The United States will increase military aid to Tunisia threefold this year and help train its troops, a senior U.S official said on Friday, weeks after the country suffered its deadliest attack in more than a decade.

The U.S. government aimed to provide Tunisia with more equipment, weapons and technical support, U.S. deputy secretary of state Antony Blinken said.

"Our goal is to enhance their ability to defeat those who threaten the freedom and safety of the nation," he told a news conference after meeting Tunisian Prime Minister Habib Essid.

But it has also seen a rise in rebel forces, and last month gunmen stormed the national Bardo museum in the capital Tunis, killing 21 foreign tourists in an attack for which ISIL claimed responsibility.

Tunisian authorities are concerned that violence will spill over from Libya too, where two rival governments and several armed groups are embroiled in a bitter power struggle four years after the ousting of Muammar Gaddafi.

Blinken said the Obama administration would offer the Tunisian army training in border management, the first time it will be involved in training Tunisian soldiers.

Blinken gave no figure for military aid, which he said would rise 200 percent in 2015. Another U.S. official said last year's package amounted to $60 million.

Japanese, Polish, French and Colombian tourists were among those killed in the museum attack, which Tunis said fighters from the Okba Ibn Nafaa group, concentrated in the Chaambi mountains bordering Algeria, were also involved in.
